摘　　要：在光通信系统中,量子效率和响应速率是光电探测器的2个重要的参数,要获得高的量子效率就必须增大吸收层的厚度,而增大吸收层的厚度将导致载流子渡越时间的延长,从而使响应速率下降.谐振腔增强型光探测器(Resonant Cavity Enhanced Photo Detector,简称REC)可以有效地解决量子效率与响应速率之间相互制约关系.笔者从实际的长波长RCE出发,充分考虑器件制备的工艺难度,综合分析其各方面因素,并对器件整体设计进行优化.In a light communication system, two important ~rmneters of the photoelectricity detector are quanta efficiency and respond rate. The thickness of the absorb layer must be augmented to obtain higher quanta efficiency, which prolongs the transit time of the carriers, thus slowing the respond rate. RCEPD can solve the problem of the restriction between the quanta efficiency and the response rate. In this paper, the author design a long wavelength RCEPD, and with sufficiently considering the difficulties in the making craftwork, and analyzing the factors of RCEPD in each aspect, we optimize the whole design.
