论文摘要
在室温下，在蓝色光谱范围内的SI上的Ingan/gan量子孔的III氮化物微波孔中证明了在脉冲光泵下的低阈值激光。已经达到了18 kW/cm2的阈值，以及狭窄的线宽为0.07 nm，大峰到背景动态的较大线宽。我们将此阈值范围与可以使用速率方程模型计算的阈值进行比较。我们表明，在室温下，III氮化物量子井可以实现的最佳阈值构成了最好的阈值。还讨论了激光对制造过程的敏感性。
Low-threshold lasing under pulsed optical pumping is demonstrated at room temperature for III-nitride microdisks with InGaN/GaN quantum wells on Si in the blue spectral range. Thresholds in the range of 18 kW/cm2 have been achieved along with narrow linewidths of 0.07 nm and a large peak to background dynamic of 300. We compare this threshold range with the one that can be calculated using a rate equation model. We show that thresholds in the few kW/cm2 range constitute the best that can be achieved with III-nitride quantum wells at room temperature. The sensitivity of lasing on the fabrication process is also discussed.
