Abstract
An optically-controlled switch and a method therefor are provided. The optically-controlled switch includes a printed circuit board (PCB) including upper and lower layers and a dielectric layer between the upper and lower layers, a plurality of vias electrically connected to the upper and lower layers and located in at least two rows, a shunt via electrically connected to the lower layer and separated from the upper layer by a dielectric gap, and a photoconductive semiconductor element (PSE) electrically connected to the upper layer and the shunt via, wherein the PSE includes a dielectric state and a conductor state, and wherein an electromagnetic wave provided to the optically-controlled switch propagates or is blocked through a waveguide formed between the at least two rows.
