Abstract
This paper describes experimental results and theoretical modeling of optically controlled Dielectric Resonator Oscillator (DRO) and Gunn oscillator circuits operated at X-band. A commercially available DRO device was modified to facilitate the optical control of its output characteristics. The device was found to be optically tunable up to 15 MHz and FM rates up to 130 MHz were observed. The Gunn Oscillator circuit was designed in a microstrip configuration. A high resistivity Si wafer was incorporated in the resonant cavity as the optical tuning element. The circuit was tuned in excess of 10 MHz. The operation of these devices were modeled using analytical and computer aided design techniques and showed good agreement with the experimental results.
