Photonic crystal slab nanocavities containing one layer of quantum dots have exhibited: strong coupling to a single quantum dot; tuning by condensation of xenon gas; linewidth broadening due to ensemble dot absorption; gain and lasing.
Optical characterization of a novel type of semiconductor microcavity based on a fully-buried, all-epitaxial design reveals many properties essential for a manufacturable technology. We demonstrate detailed mode-imaging, lasing, as well as a sizeable Purcell effect.
