摘要

设计、制作了具有偶极子掺杂结构的单行载流子光电探测器(UTC-PD)，并对其进行了表征。利用等效电路模型提取了器件传输时延和RC时延。当结反偏置大于4 V时，传输延时小于4.5 ps。结果表明，偶极掺杂可以有效地抑制InGaAs/InP界面的电流阻塞。

Analysis of uni-traveling-carrier photodetectors (UTC-PDs) with dipole-doped interface

A uni-traveling-carrier photodetector (UTC-PD) with dipole-doped structure at the InGaAs/InP interface has been designed, fabricated and characterized. The device transit time delay and RC time delay was extracted using an equivalent circuit model. A transit time delay time less than 4.5 ps was obtained with a junction reverse bias lager than 4 V. The results suggest that the current-blocking at InGaAs/InP interface can be effectively suppressed by the dipole-doped interface.
