Abstract
We report enhanced amplified-spontaneous-emission from CdSe/ZnS quantum-dots in an all-dielectric Si3N4/SiO2 microcavity. Directional emission is observed through the cavity mode. Enhancement is confirmed with time-resolved and steady-state photoluminescence measurements showing a Purcell factor of ~1.3.
