Abstract

We demonstrate uni-directional emission near 400 nm from lasing InGaN/InGaN multiple quantum-well (MQW) spiral micropillars. Reduction of the lasing threshold (to current densities as low as 4.6 kA/cm/sup 2/ when current-injected) and enhancement of uni-directionality occurs when the microcavity is selectively optically or electrically pumped near its boundary.

单向蓝光发射螺旋形微柱激光二极管

我们演示了InGaN/InGaN多量子阱(MQW)螺旋微柱激光在400 nm附近的单向发射。当微腔在其边界附近选择性地进行光学或电泵浦时，激光阈值降低(注入电流时电流密度低至4.6 kA/cm/sup /)，单向性增强。
