High-Q whispering gallery modes in pillar microcavities

Abstract

We report the observation of high-Q whispering gallery modes (Q > 10 000) in GaAs/AlAs pillar microcavities containing InAs quantum dots as an internal probe. A simple model based on the effective index method describes precisely the evolution of the free spectral range with the pillar diameter.
