Abstract
An optically controlled switch includes a substrate integrated waveguide (SIW) including: a first port and a second port, the first port and the second port being located at ends of the SIW to input and output an electromagnetic wave; and a shorting via electrically connected to a bottom layer of the SIW and separated from a top layer of the SIW by a dielectric gap. The optically controlled switch includes: a photoconductive element located on the top layer of the SIW and electrically connected to the shorting via and the top layer of the SIW, the photoconductive element being configured to have a dielectric state and a conductor state depending on a state of a controlling light flux; and a cutoff waveguide formed around the dielectric gap and the photoconductive element, and configured to provide control of the photoconductive element from a light source and block parasitic radiation.
