摘要

在小输出光电流(0.4 mA)和零偏置工作下，GaAs/AlGaAs UTC-PD具有较强的带宽增强。等效电路建模结果表明，这种效应是由于吸收层内部的自感场造成的，有利于器件在零功耗下的高速性能。

Strong bandwidth-enhancement effect in high-speed GaAs/AlGaAs based uni-traveling carrier photodiode under small photocurrent and zero-bias operation

Strong bandwidth-enhancement has been observed in GaAs/AlGaAs UTC-PD under small-output-photocurrent (0.4 mA) and zero-bias operation. Equivalent-circuit-modeling results indicate that such effect is due to self-induced-field inside absorption layer, which benefits devices' high-speed performance under zero-power-consumption operation.
