Abstract

We describe studies on the photonic quantum ring (PQR) of whispering cave modes (WCMs). Low PQR threshold currents and thermally stable spectra derive from a photonic quantum corral effect via strong carrier-photon couplings which is induced by dominant polarization state along the quantum ring. The PQR emission is surfacenormal dominant with controllable divergence properties which may replace LEDs. For high power PQRs, we develop flower-type PQR lasers. Also next-generation light sources for 3D TV and bio-photonics are summarized.
