Bistability of currents passing LD in wavelength tunable external cavity

摘要: 预测了由于半导体激光二极管(LD)的准费米能级随LD内载流子密度变化,因而,在调谐外腔半导体激光器的输出功率振荡频率曲线上出现双稳环的时候,通过LD的电流也应出现一个伴随的双稳环.Abstract: Because quasi-Fermi levels of a laser diode(LD) vary with the carrier density,it is predicted that a hysteresis loop should occur for the current passing LD while a hysteresis loop appears for the power-frequency curve of a tunable external cavity semiconductor.
