Characterization of a Sub-THz Photonic Transmitter Based on a Sep arated-Tran sp o rt-Recombin ation Photodiode

Abstract

By incorporating low-temperature-grown GaAs based separated-transport-recombination photodiode with micromachined antenna, such photonic-transmitter can radiate strong sub-THz waves at designed frequency (similar to 500GHz) without using Si-lens. Problems of device saturation under high bias voltage were also eliminated. (C) 2005 Optical Society of America
