Abstract :
We will review the recent progress in high speed, high power photodetectors. The design trade-offs among the saturation power, 3-dB bandwidth, and quantum efficiency will be described. The fundamental limit of saturation powers for various types of photodetectors, including surface-illuminated p-i-n photodetectors, waveguide photodetectors, traveling-wave photodetectors, and velocity-matched distributed photodetectors, will be derived and compared.
