N-Bit Optically Controlled Microwave Signal Attenuator Using The Photoconductive Effect

Abstract

Various optical architectures for N-bit digital control of microwave signals are introduced that use the photoconductive (PC) effect in microwave waveguides for variable rf attenuation control. A 2-bit optically controlled microwave attenuator based on a silicon PC transmission line device is experimentally demonstrated at 990 Mhz. At 532 nm, this attenuator provided 0, 5.8, 11.2, and 15.6 of attenuation levels.
