Abstract
We present classical and quantum light generation based on various types of group III-nitride micro- and nano-structures. We fabricated three-dimensional GaN-based pyramidal, annular, columnar, and tapered rod structures, on which InGaN/GaN quantum wells structures were grown by metal-organic chemical vapor deposition. We demonstrate phosphor-free white-color light emission with pyramidal and annular structures, unidirectional light propagation in energy-gradient, tapered core-shell rod structures, ultrafast single photon generation from a quantum dot formed at the apex of pyramid structures, and exciton-polariton formation at room-temperature in bulk GaN and GaN/InGaN core-shell rod structures.
