Quantum Photonics and the Physics of Light

We propose an integrated five-year research program that spans research topics ranging from fundamental aspects of optical physics to aspects of applied engineering photonics. Within this broader context, this document highlights two specific research projects. One entails studies of a photonic material recently uncovered by the PI that possesses an extremely large (largest ever measured!), ultrafast nonlinear response associated with its epsilon-near-zero (ENZ) spectral region. We will study the nature of this huge nonlinear response, its implications for photonics applications, and the novel physics permitted by the combination of small dielectric permittivity and large nonlinearity. The other project entails the use of nanofabrication methods to manufacture new photonic surfaces, structures and devices. A particular goal of this part of the work is to develop a miniature, chip-scale spectrometer. A spectrometer of this sort holds great promise for the betterment of society, including the development of portable diagnostic equipment for the health sciences and field-ready equipment to thwart terrorism threats.
