Abstract: The optoelectronic switch includes a photosensitive GaAs FET (1) on to which an optical signal (11) may be directed. The optical signal (11) is derived from an RF modulated light source (12). A voltage circuit (7) is connected to the FET (1) to switch the FET (1) "on" or "off" by placing a positive or zero voltage respectively on the drain. An isolation of over 70 dB is obtained in this FET switch,
