A few years ago, researchers in Michal Lipson’s lab came across something unexpected. Their work at the time focused on improving LiDAR, a technology that measures distance using lightwaves. The team ...
Abstract: Improving optical confinement and threshold currents has been the main focus of AlGaN-based deep-ultraviolet (DUV) laser diode (LD) optimization. In this paper, an inverted trapezoidal hole ...
Abstract: In this paper, we proposed two kinds of graded AlInGaN last quantum barrier (LQB) structures to improve the optical performance of deep ultraviolet laser diodes (DUV LDs). Through the ...
