摘要

采用漂移扩散模型和能量平衡模型研究了大功率激光晶闸管中激光的产生和电流动态。结果表明，漂移扩散模型明显高估了冲击电离过程在窄异质结电场区的贡献。利用能量平衡模型可以得到与实验结果接近的激光晶闸管模拟动态。

Simulation of the AlGaAs/GaAs laser thyristor turn-on dynamics using energy-balance model

The laser generation and the current dynamics in high-power laser-thyristor is studied using drift-diffusion and energy-balance models. It is observed that the drift-diffusion model significantly overestimates the contribution of impact ionization process in a narrow heterojunction electric field region. The use of the energy-balance model allows us to obtain the simulated laser-thyristor dynamics close to the experimental one.
