Title: Traveling-wave photodetector for 1.55 {mu}m wavelength fabricated with unitraveling-carrier photodiodes

Abstract

We report on a periodic traveling-wave photodetector (P-TW-PD) fabricated by unicarrier traveling photodiodes (UTC-PDs). It is comprised of three UTC-PDs periodically arranged along a coplanar waveguide transmission line. The photoresponse of the P-TW-UTC-PD is three times that of a single UTC-PD. A 3 dB bandwidth (f{sub 3dB}) of 115 GHz at 1.55 {mu}m was observed in a P-TW-UTC-PD with a terminal resistor located at the input end. This value of f{sub 3dB} is almost the same as that observed in a single UTC-PD. In P-TW-UTC-PDs with no terminal resistor, the 3 dB bandwidth degrades to 56 GHz as a result of the reflection of backward-propagating microwaves at the input end. We conclude that our P-TW-UTC-PD provides velocity matching between electrical and optical waves. {copyright} 2001 American Institute of Physics.
