  • Abstract
    Reconfigurable, optically tuned dual-band branch-line couplers with photoconducting switches are presented. Tunability is achieved by increasing the power of the laser applied to the highly resistive silicon wafer and changing the properties of silicon under optical illumination. A frequency shift of 30% is achieved from all switches off to all switches on in both frequency bands.
