We for the first time present designs of high-Q photonic crystal nanocavities in the cases previously rendered ldquoimpossiblerdquo, including an ultra-high Q dual-polarized nanocavities, high Q/V cavities based on low-index materials, and high-Q air-band-mode cavities.
We theoretically demonstrated high quality factor (Q~250,000) micropillar cavities with record low mode volume for a 340 nm diameter titania/silica micropillar. It represents a three orders of magnitude Q/V enhancement compared to any previous micropillar cavities.
Optical loss of a chemically-synthesized light-emitting nanowire can be reduced by embedding the nanowire in an optical microcavity. Design of nanowire/photonic crystal platform as well as characterization of nanowire embedded in race-track microresonator are presented.
Photonic crystal laser platform, that enables efficient current injection, is reported. Holes are etched perpendicular to the surface of the sample in order to open photonic bandgap for TM-polarized light emitted from quantum cascade laser.
