Method of Rapid Nanophotonic Design and a Nanophotonic Waveguide to Fiber Coupler

Wed, 2018-06-13 17:44
ua18-119 - Title:  Method of Rapid Nanophotonic Design and Nanophotonic Coupler   Invention:  Researchers at the University of Arizona have developed a rapid design approach for designing nanophotonic devices.  The invention is a novel implementation of  an iterative optimal approach related to the known coupled dipole modeling approach.  The novel implementation is several orders of magnitude faster than finite difference time domain approaches.   Background:  Most current approaches to the design of nanophotonic devices are based on 2D systems and use slow simulation routines such as finite difference time domain (FDTD).  While these approaches are suitable for the design of 2D structures using lithographic approaches, they are not well suited for the design of 3D structures.   Applications: *  biological sensing *  optical computing *  superresolution microscopy *  compact waveguide-to-fiber couplers   Advantages: *  several orders of magnitude faster than conventional approaches *  better performance of 3D nanostructures   Contact:  Amy Phillips amyp@tla.arizona.edu Refer to case number UA18-119    

Low-Cost, Compact Chromatic Confocal Microscope

Wed, 2018-06-13 17:44
ua18-151 - Title: Low-Cost, Compact Chromatic Confocal Microscope   Invention: Researchers at the University of Arizona have designed a high light efficiency, high resolution confocal microscope that has no moving parts. The new design is high-speed, has axial scanning, is compact, and low-cost.   Background: Current state-of-the-art scanning confocal microscopes use axial and lateral scanning techniques, such as DMDs for lateral scanning and a tunable light source and chromatic objective lens for axial scanning.  These methods are faster than prior efforts, but are expensive and have low light efficiency.  MEMS pinhole arrays have also been used for snapshot 3D imaging, but the lateral resolution is low and also suffers low light efficiency.  Light source arrays have improved the light efficiency, but do not adequately address the axial scanning.

Wed, 2018-06-13 17:44
ua18-153 - Title: Identification and Control of Myopic Progression Using Distortion   Invention: This technology is a method and system to measure eye distortion due to myopia. The system is used to develop novel lenses and therapies to correct and/or stop the distortion’s progression in patients.   Background: Current solutions for measuring one’s eye distortion do not consistently work for individuals, allowing instead the progression of myopia to continue and become more severe. The technology presented here provides a solution for measuring and assessing early onset myopia with the goal of stopping its progression.   Applications:   Advantages:   Licensing Manager: Amy Phillips AmyP@tla.arizona.edu

Attomicroscopy: Attosecond Electron Microscopy and Diffraction

Wed, 2018-06-13 17:44
ua18-172 - Title: Attomicroscopy: Attosecond Electron Microscopy and Diffraction   Invention: This technology introduces additional novel compontents to the conventional optical gating technique and results in electron pulses of less than 20 femtoseconds and even into the attosecond realm. This provides improved temporal resolution for imaging done by electron microscopy and diffraction imaging.   Background: Traditional electron microscopes are limited in their temporal resolution. The current state of the art has only achieved 200 femtosecond electron pulse widths.  Using faster optical pulses to gate the electron pulses has been limited by the limitations on the optical pulse widths to drive the gating.   Applications:   Advantages:   Licensing Manager: Amy Phillips AmyP@tla.arizona.edu

Snapshot Interferometer for Surface Profile and Roughness

Wed, 2018-06-13 17:44
ua18-175 - Title: Snapshot Interferometer for Surface Profile and Roughness   Invention: Researchers at the University of Arizona have designed an instrument that can take a “snapshot” of a surface’s profile and roughness simultaneously.  The non-contact metrology tool is high speed with high sensitivity, precision, and resolution.  It can be used with a variety of light sources across various applications.   Background: Metrology is an integral part of the automated manufacturing process. As new processes become automated, new technology must be developed to handle the imaging of more complex parts quickly, while being low-cost, scalable and, in many cases, portable. Instruments exist to measure either surface profile or surface roughness, but it would be more cost efficient to have a single instrument which could do both.   Applications:   Advantages:   Licensing Manager: Amy Phillips AmyP@tla.arizona.edu

Stochastic Bag Generator (Sbg)

Wed, 2018-06-13 17:44
ua18-177 - Title: Stochastic Bag Generator (SBG)   Invention: This technology is a method of modeling the response of a luggage inspection device based on a variety of contents and packing styles.  The method is used to calibrate inspection instruments' responses, and predict successful inspection.  This allows for better inspection machine design, decreases the number of bags pulled for secondary screening, and increases the effectiveness of identifying threats.   Background: Every year, millions of bags are screened at airports, ports of entry, and even when entering high-security buildings. Bags are often flagged as containing a suspicious item but after a manual check of the bag, the bag actually doesn’t contain any harmful items.  This increases the inspection time and is vulnerable to mistakes.   Applications:   Advantages:   Licensing Manager: Amy Phillips Amyp@tla.arizona.edu

Rotationally Shift Invariant Optical System

Wed, 2018-06-13 17:44
ua18-207 - Title:  Rotationally Shift Invariant Optical System   Invention:  Researchers at the University of Arizona have designed a highly sophisticated LiDAR system that uses a novel optical phased array transmitter in conjunction with a novel spherically shift-invariant (SSI) receiver system to provide depth information over a large 2D scene in a single snapshot.  The field of view of the receiver is increased by the novel optical design to properly focus incoming light from a large set of angles. The system also improves the depth resolution and reduces position ambiguity.   Background: Optical phased arrays have been used for increasing the speed and field of view of LiDAR systems, but the element to element spacing is too large, leading to reduced range and target position ambiguity.  For some applications, SSI systems can increase the field of view, but at large angles, the focal point quickly moves away from the centerline.   Advantages: *  Fast scanning *  Huge field of view *  High resolution with enhanced position accuracy   Applications: *  LiDAR *  Autonomous driving vehicles *  Remote sensing   Contact: Amy Phillips aphillips@optics.arizona.edu Refer to case number UA18-207

Multi-Static/vlbi Imaging Radar for Characterizing Space Objects

Thu, 2018-04-12 17:45
ua18-117 - Title: Multi-Static/VLB Imaging Radar for Characterizing Space Objects   Invention: This invention is a methodology for using multi-static, long baseline imaging radar for the tracking, imaging and classification of Near-Earth Objects (NEOs).   Background: Since the launch of Sputnik in 1957, mankind has progressively added more satellites, and consequently more debris, into Earth’s orbit. As of 2013, NASA has tracked over 500,000 pieces of debris larger than the size of an average marble, and this number is constantly increasing. The amount of satellites and debris have posed a problem with the ability to track and image objects, especially those that are small but still problematic because of their high speed. Traditional techniques for tracking these satellites are not sufficient enough to provide high-resolution images, meaning small objects are often missed. The technique presented here will allow researchers and defense agencies to locate space objects and track them in a more timely manner.   Applications:   Advantages:   Licensing Manager: John Geikler JohnG@tla.arizona.edu (520) 626-4605

Method for Detection of Defects in Semiconductors Using a Novel Multiphoton Microscope

Wed, 2018-04-11 09:03
ua18-096 - Title:  Method For Detection Of Defects In Semiconductors   Invention:  This is a system that uses a multi-photon microscope to scan and detect defects in thin films of semiconducting materials including polymers and crystals.  The novel detection technique identifies areas exhibiting anomalies for further inspection with 2 micron resolution.   Background:  Conventional methods of measuring a spectrum from a sample using multi-photon microscopy (MPM) typically involve setting galvanometers at their highest speed with lowest pixel resolution to scan a whole area quickly,  But that imaging technique takes an average of the surface of the sample and does not properly illuminate certain regions for a sufficient period of time to catch all defects.  Random sampling also misses many defects.   Applications: *  Defect detection in materials   Advantages: *  Higher detection rate *  Provides analysis of the defect *  Works for silicon wafers, amorphous silicon, thin films of polymers and copolymers, blends that include fullerenes,  and semiconductor crystals   Contact:  Amy Phillips amyp@tla.arizona.edu Refer to case number UA18-096    

Polygon X-Prism for Imaging and Display Applications

Wed, 2018-04-11 09:03
ua18-132 - Title:  Polygon X-Prism for Imaging and Display Applications   Invention:  The invention is a prism with more than three output facets, by including additional optical interfaces inside the cube.  For example, all six facets of the cube can be used such that one facet is the input and five facets are the outputs.  The invention can apply to even large polygonal prisms, utilizing all facets of the polygonal prism.   Background:  A conventional x-prism splits an incoming light beam into three beams with equal path lengths and different directions.  When operated in revers, the x-prism acts as a combiner that combines three lights beams from different directions into one beam with equal path lengths.  In some applications, however, it is beneficial to split an incoming light beam into more than three components using a passive optical element that has a compact form factor.    Applications: *  multi-color projectors *  passive optical routers *  beam combiner *  full spectrum camera *  imaging polarimeter   Advantages: *  passively splits or combines beams *  compact   Contact:  Amy Phillips amyp@tla.arizona.edu Refer to case number UA18-132

Polarization Preserving Bidirectional Isolator

Wed, 2018-04-11 09:03
ua18-066 - Title:  Polarization Preserving Bidirectional Isolator   Invention:  The invention is a bidirectional isolator that can be a stand-alone component, or used to stabilize the output of  a bi-directional ultra fast fiber laser.  The use of the isolator in such a laser allows the various modes to oscillate with fixed phases with respect to one another and constructively interfere with one another, producing an intense burst or pulse of light.    Background:  Polarization effects can cause unwanted power and frequency modulation in laser systems generally.  In bi-directional lasers, this can cause the lasers to become unstable.  Conventional means of isolating the polarization state of the light within the bidirectional laser are expensive and difficult to align.   Applications: *  Bi-directional ultra fast pulsed lasers *  Spectroscopy *  Precision range-finding *  Pump-probe experiments using asynchronous sampling Advantages: *  Inexpensive and compact *  Easier to align, and keep aligned *  Accommodates self-starting *  Low insertion loss, high extinction ratio   Contact:  Amy Phillips amyp@tla.arizona.edu Refer to case number UA18-066  

Multi-Zone Diffractive Mask for Fine Control of Light Amplitude and Phase

Wed, 2018-04-11 09:03
ua15-207 - Title: Diffractive Optical Element for Blocking Light Invention: The invention is a mask that can be used in an optical setup to diffract an amount of light based on wavelength. The mask is placed within the focal plane to solve the size-chromaticity problem by using this phase technique. This will achieve better resolution and high start to planet contrast. Background: In the study of the Sun’s corona, light from the central portion of the sun needs to be blocked while the light of study needs to be transparent. A coronagraph achieves this. In addition, exoplanet finding is extremely popular but is also negatively affected by unwanted starlight. Masks that diffract light at certain wavelengths can help detect planets previously hidden by starlight. Applications: Advantages:

Bidirectional Self-Starting Ultrafast Fiber Laser

Wed, 2018-04-11 09:02
ua18-067 - Title: Bidirectional Self-Starting Ultrafast Fiber Laser   Invention: This technology is a bidirectional, self-starting, ultrafast fiber that has a mode-locked operation that is assisted by polarization multiplexing optical fibers. It has a specialized non-reciprocal element, which assigns a polarization to a propagation direction and forces the laser to operate in two separate polarizations in at least one part of the cavity.   Background: Starting mode-locked operation in a bidirectional fiber laser requires a control system or a technician, and fiber laser systems are typically complex in design. Alignment is difficult and needs to be tweaked often. The invention presented here has solutions for both of these issues by being self-starting and utilizing components that drastically simplify the system design and alignment.   Applications:   Advantages:   Licensing Manager: Amy Phillips AmyP@tla.arizona.edu

Amplification of the Incidence Angles of a Light Beam to Cover Up to 4pi Steradians

Wed, 2018-04-11 09:02
ua18-108 - Title: Amplification of the Incidence of a Light Beam to Cover Up to 4Pi Sterdians   Invention: The invention employs a means of preventing total internal reflection and allows the beam to exit the material to steer at a wider diffraction angle, increasing the incidence angle of a light beam for spatial light modulators and integrated phase arrays.   Background: Non-mechanical beam steering requires efficient diffraction and a high angle of incidence. At high angles, the diffracted beam becomes trapped between interfaces and can’t exit the material. To allow access to the beam, total internal reflection must be avoided.   Applications:   Advantages:   Licensing Manager: Amy Phillips AmyP@tla.arizona.edu

Calibration Method for Photon Counting Detectors

Wed, 2018-04-11 09:02
ua18-137 - Title: Calibration Method for Photon Counting Detectors Invention: This technology is a calibration method that could be a game changer for adoption of photon counting-based imagery. It solves long-standing challenges in the calibration of detectors used in medical imaging devices and is also useful for security screenings and other imaging photon counting detectors. The present method is simple to use, requires less time than conventional calibration methods, and is easy to implement, while also pushing the current state of the art into additional applications. Background: The calibration process for photon counting-based imagery has been a hindrance to its broader adoption.  The relative signal strengths of the light sensors within the photon counting detectors are used to estimate the position and energy attributes of each gamma-ray interaction.  Several methods consisting of simple linear combinations of signals are conventionally used to estimate gamma-ray interaction position for monolithic crystal gamma-ray detectors.  In order to apply these methods, detector calibration is necessary to determine the detector sensors response as a function of gamma-ray interaction position.  However, each of these methods has significant disadvantages, such as being very time consuming or being unable to calibrate depth of interaction information. Accordingly, what is needed is an improved method for calibrating gamma-ray and photon counting detectors. Applications: Advantages: Licensing Manager: Amy Phillips AmyP@tla.arizona.edu
