Colloquium

Molecular interfaces play a dominant role in much of Chemistry, and are of vital importance in diverse applications such as sensing, catalysis and electron transfer. Yet the mere fact of coupling two fundamentally different materials, e.g. a molecular solid with an inorganic substrate, makes...

Frequency synthesis is ubiquitous in all aspects of our modern technological society, with examples being found in wide ranging applications from computing, communications and navigation systems to sensors and scientific instrumentation. Historically, the generation and precise control of...

Following a brief introduction to the II-VI organization, this presentation will describe how, over the past 25 years, the advancing technology needs of the CO2 Industrial Laser Market drove II-VI to be an early adopter of freeform diamond turning technologies including Fast Tool Servo (FTS) and...

The microelectronics revolution has been ongoing now for more than 50 years.  The pace of progress, described as “Moore’s Law”, is an observation and expectation of microcircuit performance and value that doubles every two years.  My talk will focus on the evolution...

This presentation is an overview of femtosecond laser applications in refractive vision correction surgeries and laser cataract surgeries. I will also discuss briefly about how an engineering student can transition effectively to a performer in the industry.

Integrating cold atoms with nanophotonics enables the exploration of new paradigms in quantum optics and many body physics. Advanced fabrication capabilities for low-loss dielectric materials provide powerful tools to engineer band structure and light-matter couplings between photons and atoms....

Spectrally encoded confocal microscopy (SECM) uses a diffraction grating and broadband light source to conduct line confocal imaging without using any beam scanning device. SECM has two major advantages over conventional confocal microscopy devices: i) imaging speed can be increased by orders of...

Hiding transmitted signals is of paramount importance in many communication and sensing settings. In communications, traditional security (e.g., encryption) prevents unauthorized access to message content; however, detection of the mere presence of a message can have significant negative impact...

Optical fiber communication is a rapid-growth industry in the past 25 years, for it provides enormous bandwidth, and the optical fiber is the only medium which can transport massive amounts of data over long distance. Combining the DWDM (Dense-Wavelength-Division-Multiplexing) technology and the...

Fluorescence microscopy allows targeted observation of structures and molecular processes in living systems. It provides essential information for understanding how biological systems function.  3D imaging the dynamics of a living system is challenging due to tissue scattering, a limited...

At the U of A, Meinel is best known as the founder of the College of Optical Sciences. But before he came to the University of Arizona, first as Department Chair of Steward Observatory and then chair of the optical sciences center he was the founding director of Kitt Peak National Observatory...

Ultrashort optical pulses have found important applications in material processing, precision measurements, time keeping, and multiphoton microscopy. In this presentation, I will discuss our research results in the development of compact fiber lasers that emit ultrashort optical pulses in the...

Quantum mechanics has been the "theory of everything" for about a century, accounting for the behavior of light and matter at all scales from the microscopic to the macroscopic. Modern physics is now increasingly focused on a new challenge: how do we make quantum systems behave the way...
