Abstract:
An optoelectronic switch comprising:an input signal port and an output signal port;at least two PIN diodes connected in series with opposed polarity and terminated at one end each by a PIN diode junction and at the opposite end each by the input signal port and the output signal port respectively;a photovoltaic cell terminated at one end by the PIN diode junction for generating a PIN diode bias current to switch the PIN diodes between a substantially conductive state while the photovoltaic cell receives optical energy and a substantially non-conductive state while the photovoltaic cell does not receive optical energy;an input signal choke terminated at one end by the input signal port and at its opposite end by an opposite end of the photovoltaic cell for presenting a high impedance to an input signal and a low impedance to the PIN diode bias current;and an output signal choke terminated at one end by the output signal port and at its opposite end by the opposite end of the photovoltaic cell for presenting a high impedance to an output signal and a low impedance to the PIN diode bias current.
