InGaAs/InGaAsP/InP SAGM-APD for Long-Haul High Bit Rate Optical Fiber Communications

InGaAs/lnGaAsP/InP分隔吸收区、梯度区、倍增区的雪崩光电二极管(SAGMAPD)具有小的暗电流、低的雪崩倍增噪声和高的增益-带宽乘积。它是应用于长距离和高比特率(几Gb/s)光纤通信的最佳光检测器之一。本文综述这种器件的结构、工作原理和特性及其研究进展。

InGaAs/InGaAsP/InP seperate absorption, grading and multiplication avalanche photodiodes (SAGM-APD's) have low dark current, low multiplication noise, and high gain-bandwidth product. They are one of the best detectors for long-haul high bit rate (multigigabit per second) optical fiber communication. This paper summarizes the structures, the operating principles and charactaristics, and research progress of these devices.
