摘要

应用LASTIP软件模拟了经典的氮化镓基蓝色激光二极管(LD)，发光波长约为410nm。考虑极化电荷(PC)的影响，理论模拟结果与实验结果一致。另一方面，在不考虑PC的情况下，阈值电压和电流降低，而激光特性温度升高，表明PC对激光性能起负作用。

Effects of polarization charge in GaN-based blue laser diodes (LD)

LASTIP software was applied to simulate a classical GaN-based blue laser diodes (LD) emitting at about 410nm. Considering effects of polarization charge (PC) in this LD, theoretical simulation showed accordant results with that in experiments. On the other hand, without regard to PC, threshold voltage and current are lowered, while laser characteristic temperature is enhanced, which indicates that PC acts as a negative role for laser performance.
