采用改进的双层有源层结构，研制了单片电吸收调制分布反馈（DFB）激光器，阈值电流38 mA，消光比9dB在0.5V ~ 3.0V电压范围内，在100 mA工作电流下，获得了约5 mW的输出功率（在相同工作电流下仅为1.5mW），提高了器件的输出功率。
Monolithic electro-absorption modulated distributed-feedback(DFB) lasers are proposed and fabricated by using a modified double stack active layer.The 38mA threshold,9dB extinction ratio (from 0.5V to 3.0V),and about 5mW output power at the 100mA operation current are achieved.Compared with other reported results (only 1.5mW at the same operation current) of the traditional stack active structure,the proposed structure improves the output power of devices.
