Assignee: THE REGENTS OF THE UNIVERSITY OF CALIFORNIA
Field: Telecommunications (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 9:
10. A method of switching radio frequency electrical signals, comprising:
receiving a radio frequency input signal at an input port; and
controlling an electrical conduction of the radio frequency input signal through a photoconductive patch via an optical power carried in an optical waveguide and applied to the photoconductive patch,
wherein the photoconductive patch electrically connects the input port to an output port providing the radio frequency signal at the output port when a threshold optical power is passed through the optical waveguide, and the photoconductive patch electrically isolates the input port from the output port when less than the threshold optical power is passed through the optical waveguide,
wherein the optical waveguide extends to another optical waveguide corresponding to another optically controlled electrical switch device.
