High-Power and High-Responsivity Photodiode for Long-Haul and Short-Reach Fiber Communication

The two major trends in the development of photodetectors (PDs) are improving bandwidth-efficiency product and obtaining high output power-bandwidth product. In this invited paper we review our recent work on PDs, which can meet these two challenges simultaneously, for the applications of 40-Gb/s long-haul and 10-Gb/s short-reach fiber communication.
