Hole emitter whispering galleries of photonic quantum ring
Abstract
We report on the first observation of hole whispering gallery lasers from semiconductor microcavities with three dimensional optical confinement, with thresholds potentially reducible to micro-to-nano ampere regimes according to a quadratic size-dependent reduction, due to ideal quantum wire properties of the naturally formed photonic quantum rings before imminent recombination in a dynamic steady state fashion. If the device size grows over a critical diameter, the quantum ring whispering gallery then begins to disappear. However, cooperative small hole arrays like 256x256 quantum ring emitters avoid the criticality and open a possibility of constructing practical dense electro-pumped micro-to-nano watt emitter arrays, amenable to mega-to-giga ring emitter chip development via present fabrication techniques.
