Optical characterization of high quality two dimensional photonic crystal cavities

Abstract

Photonic crystal nanocavities have recently attracted much attention because such cavities are predicted to provide the desired combination of both small mode volume and high Q values. In this presentation, we report the experimental demonstration that by using fractional edge dislocations in photonic crystal cavities, it is possible to construct microcavities with high Qs as well as small mode volumes.
