An opto-electronically controlled waveguide includes a waveguide a finline mounted in the waveguide a photovoltaic switch operably electrically connected 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.
