ABSTRACT

Abstract

As we embark on a journey into the nanophotonics world, we are at a time of unique opportunity analogous to the rocketing of technology that took off in the 60's around microelectronics and integration. Photonics and nanoscale integration is becoming more ubiquitous and will continue to do so. However, understanding the electromagnetic (EM) processes in nanostructures and nano-particles, in which materials exhibit novel properties due to their small size, presents many fundamental challenges. This talk discusses some of the unique complexities and opportunities that arise when studying and exploiting light-matter interactions in photonic nanostructures. Based on some of our recent theoretical and numerical modeling work, several important topics with EM interactions in nanostructures will be introduced, including: a) The role of manufacturing disorder on optical scattering loss in photonic crystal waveguides and b) Modified spontaneous emission dynamics from single quantum dots using high quality-factor optical nanocavities. Applications will be emphasized throughout and a close connection to recent experiments will be made or shown directly.
