The concept of photoconductivity is utilized in a number of microwave applications such as switchesand attenuators. Optically controlled microwave attenuators prove an alternative to the conventionalattenuators due to their simplicity, easy of operation, and very narrow ranges of continuously varyingattenuation levels available. This paper describes the design of such configurations of optically controlledattenuators on a microstrip line fabricated on a semiconductor substrate
