[We-P-68]Loss Analysis of a Silicon Laser Power Converter Under High Excitation Power Density Using Drift–Diffusion Model
〇Yukihiro Harada1, Ryo Yasumatsuya1, Shigeo Asahi1, Takashi Kita1 (1. Kobe Univ. (Japan))
We employ a drift–diffusion simulation framework to investigate excitation-power-density-dependent loss mechanisms in a silicon laser power converter. High excitation power density increases self-heating, reduces mobility, and causes carrier accumulation, which enhances Shockley-Read-Hall recombination and degrades fill factor.
