Abstract
An optoelectronic switch for switching an input signal comprises two PIN des connected in series with opposed polarity, an input signal choke connected to the PIN diodes for presenting a high impedance to the input signal and a low impedance to a PIN diode bias, and a photovoltaic cell connected to the PIN diodes and the input signal choke for generating the PIN diode bias to switch the PIN diodes between a substantially conductive state while the photovoltaic cell receives optical energy from a light source and a substantially non-conductive state while the photovoltaic cell does not receive optical energy from the light source.
