摘要

测量了InGaAs-InGaAsP MQW激光结构在超短脉冲激发后瞬态净增益谱的时间发展。通过理论模拟，研究了载流子密度、载流子温度和带隙重整化对瞬态增益的影响。

Transient gain-spectra and bandgap-renormalization dynamics in ultrashort optical pulse excited InGaAs-InGaAsP multi-quantum-well laser structure

Time-development of transient optical net gain spectra of InGaAs-InGaAsP MQW laser structure after ultrashort pulse excitation was measured. With theoretical simulation, the dynamics of carrier density, carrier temperature and bandgap renormalization and their influences on transient gain were investigated.
