Abstract

Recent developments in high-speed photodetectors show a trend toward high efficiency and high output voltage. The waveguide photodiode is a powerful tool for achieving both the objectives - it has a bandwidth of more than 100 GHz and an efficiency of 50%. The recently developed uni-traveling-carrier structure has boosted the output voltage of the waveguide photodiode up to 1.3V, which is high enough for directly operating a digital circuit. Another trend is toward reducing the receiver cost. As opto-electronics-integrated-circuit technology based on the waveguide photodiode becomes mature and its speed reaches the 40-GHz region, it will play an important role in constructing future high-speed systems at low cost.
