π型阵列光电探测器研究与设计
Research and design of typeπ array photodetector
摘要
Abstract
A novel arrays photodetectorbased on high order type π low pass filter circuit structure was proposed, which could achieve high output power and large operating bandwidth. According to the equivalent capacitance model of photodiode, the inductors were used to connect each photodiode in order to constitute the circuit structure which was similar to type π filter, thistype π arrayphotodetector synthesized the output current of each photodiode branch. And series capacitors were cascaded on the branch of the photodiode to increase the working bandwidth of the detector. Simulation results show that type π arrays detector’s working bandwidth is doubled compared with that of traveling-wave detector arrays (TWDA) when the capacitance cascaded in the photodiode branch is equal to the photodiode junction capacitance. Then by increasing the number of cascaded photodiode, the output power of the detector is improved, eventually, high power and large bandwidth photodetector can be designed.关键词
