Research output: Contribution to conferencePaperpeer-review


A type of ultra-high speed photodetector was presented which used low-temperature grown GaAs as the photo-absorption layer. The device structure provided microwave mode with a velocity close to the optical velocity with a wide velocity-matched bandwidth. Better bandwidth performance was recorded due to lower microwave loss, higher microwave velocity, and better impedence matching between the electrical transmission line and the external electric load.
