The evolution of fiber optic digital transmission systems toward 40 Gb/s and beyond,
the development of microwave photonics, and the emergence of multiple-component
all-optical functions has been facilitated by numerous improvements and a few
breakthroughs in photodetector and receiver technologies, the full breadth of which
would make up another book. This chapter will focus on three primary topics: high-
speed waveguide photodiodes, photodiodes with high saturati ...
