When optical components are reduced to the nanoscale, they exhibit interesting properties that can be harnessed to create new devices. For example, imagine a block of material with thin layers of alternating materials. This creates a periodic arrangement of alternating dielectric constants, forming a "photonic crystal" that is analogous to the electronic crystals used in semiconductor devices. Photonic crystals, along with quantum dots and other devices patterned at the nanoscale, may form the basis for sensors and switches used in computers and telecommunications.

Laser Filtering, Metamaterials, and Commercializing Through the Lens of the Mythical Person Month
06 Jan 2017 | | Contributor(s):: Themos Kallos
In this work we investigate whether optical metamaterials in particular may require more than the typical resources to lead to successful commercialization. We also compare the estimated efforts with other technology commercialization projects of the recent past. ...
Photonic Structures with Topological Robustness: from Classical to Quantum
06 Jan 2017 | | Contributor(s):: Mohammad Hafezi
In this talk, I demonstrate how similar physics can be observed for photons; specifically, how various quantum Hall Hamiltonians can be simulated in an optical platform. I report on the first observation of topological photonic edge state using silicon-on-insulator technology and our recent...

Optical Signal Processing of Broadband Entangled Photons
11 Jul 2016 | | Contributor(s):: Ogaga Daniel Odele
Over the last few years, our group has been involved in developing novel techniques for controlling the correlations of broadband time-frequency entangled photons (“biphotons”) using classical optical-signal processing techniques. We believe our manipulation schemes will become...
Optical Hyperspace: Light in Metamaterials with Hyperbolic Dispersion
03 Nov 2016 | | Contributor(s):: Evgenii Narimanov
The composites with opposite signs of the dielectric permittivity in two orthogonal directions, known as the hyperbolic metamaterials, represent a new "universality class" of optical media, with the light behavior which is qualitatively different from that in either metals or...
