Abstract

Multicolor (a.k.a. broadband) photodetector having a detection capability ranging from near ultra-violet to infrared can be useful as a common detector for various applications such as optical communication and optical interconnects etc. The capability of using single detector in receiver system for optical communication covering both data and transport systems, not only makes the total system cost lower, but it also makes easier the system vendors to reduce the inventory. We proposed detector having the detection capability ranging from 350 nm to 2000 nm, wavelengths that covers all optical communication wavelengths application. This invited paper has two-fold objectives: (a) provide a comprehensive overview of conventional photo detectors and their types, being used in today's optical communication and (b) introduce a development of broadband photodetector which authors pioneered. The features of proposed broadband detector are simple structure, low-cost, high quantum efficiency, high sensitivity, and high speed. Performance results will be presented along with its possible applications.
