とするオプトエレクトロニック・スイッチ回路。Consists of a light source that generates an optical signal modulated by the electrical signal to be switched, and a photodetector that receives the optical signal, converts it into an electrical signal, and turns the electrical signal on or off using a bias voltage. In an optoelectronic switch, a forward current flowing due to a forward voltage applied to turn off the photodetector changes the bias voltage of an amplifier that amplifies the electrical signal, stopping the operation of the amplifier. An optoelectronic switch circuit characterized by:
