Abstract
An opto-electronically controlled waveguide includes a waveguide; a finline mounted in the waveguide; a photovoltaic switch operably electrically cected to the finline; and a light source for generating an optical signal for modulating the photovoltaic switch. Modulation of the photovoltaic switch by intensity modulating the optical signal allows modulation of the insertion loss of the waveguide without the need for a DC bias.
