测量了光开关InGaAsP/InP激光放大器的关断时间，结果表明，该器件可以在小于自发载流子寿命的时间内关断。放大器的开关动力学的数值模拟使用货车der Pol方程与光注入和载流子密度的速率方程。模拟结果表明，器件的关断速度更快，因为它的注入电流向阈值水平增加。定性分析表明，这种快速关断是由于放大器在其激射阈值附近偏置时具有非常大的腔精细度。
Measurements of the switch-off time of an optically switched Fabry-Perot InGaAsP/InP laser amplifier indicate that the device can turn off in less than the spontaneous carrier lifetime. The switching dynamics of the amplifier are numerically modeled using the van der Pol equation with optical injection and the rate equation for the carrier density. The simulations show that the device switches off faster as its injection current is increased toward the threshold level. A qualitative analytical analysis is presented which shows that this fast switch off is due to the very large cavity finesse of the amplifier when biased near its lasing threshold.
