Integrated CMOS photodetectors for short-range optical communication

This paper presents the measured performance of different photodetector (PD) structures in a standard 65-nm CMOS technology. All photodiodes and phototransistors are tested using an 850-nm laser source through a 62.5-μm-diameter multi-mode fiber. Measurement and simulation results show that integrated CMOS photodetector with proper equalization can support > 10 Gbps systems. © 2013 IEEE
