Colloquium

The discrete electronic energy levels in atoms and atom-like systems and the ability to probe and control them using their interactions with electromagnetic fields have enabled a host of applications in quantum sensing and metrology. In this talk, I will describe the realization of quantum...

Space provides a unique experimental environment to explore fundamental physics with precision measurement tools of atomic clocks and quantum atomic sensors. With the NASA Cold Atom Laboratory launched into space on ISS, an era of atom interferometry in space has begun for science...

We use frequency-locked microtoroid optical resonators to detect protein biomarkers at attomolar to femtomolar concentrations depending on the target. We validate these results against existing sensing technologies. In addition, we present new designs to further...

Hardware architectures and technologies for AR and VR have made tremendous progress over the past 5 years, at a much faster pace than ever in history. This faster development pace was mainly fueled by recent investment hype in start-ups and accelerated mergers and acquisitions by larger...

To achieve the ambitious goal of directly imaging exo-Earths with a coronagraph, future space-based astronomical telescopes will require wavefront stability several orders of magnitude beyond state-of-the-art. Mission concepts requiring stability on the order of picometers include the Large UV/...

The Laser Interferometer Space Antenna (LISA) will enable us to listen to the low frequency/high mass gravitational wave band complementing the high frequency/low mass symphony currently received by LIGO and VIRGO. LISA will measure distance changes at the pm-level between free falling test...

Periodic arrays are an exceptionally interesting arrangement for metallic nanostructures due to their ability to support strong collective lattice resonances arising from the coherent multiple scattering enabled by the array periodicity. Thanks to these exceptional  properties, periodic...

The Advanced Technology Center (ATC) is a small R&D lab in Palo Alto, California within Lockheed Martin Space Systems Company which aims to solve challenging engineering & integration problems and provide next generation capabilities to its defense, aerospace and civilian customers. We...

Before discussing scattering, I will briefly start off talking about the meaning of Spectroscopy and what a Spectroscopist does. For some reason, the subject of light scattering in not taught in any meaningful way, especially at the Undergraduate level. But without such research, our knowledge...

Miniaturization has been a constant trend for semiconductor-based technologies such as microelectronics and photonics. One of the most important photonic components in many applications is semiconductor lasers, whose miniaturization is both important and challenging, especially in the future...
