Nanophotonic materials and devices for optical system integration

Summary form only given. We explore the unique capabilities and advantages of nanotechnology in developing next generation integrated photonic chips. For example, due to the boundary conditions on the lateral interfaces, the optical field propagating in a subwavelength periodic nanostructure will localize in a significantly different way depending on the polarization. Our long-range goal is to develop a range of photonic nanostructures - including artificially birefringent and devices, photonic crystals with defects to tailor spectral filters, and nanostructures for spatial field localization to enhance optical nonlinearities - to facilitate on-chip system integration through compatible materials and fabrication processes.
