This paper describes methods of controlling the frequency of IMPATT oscillators using optical rather than electrical signals. Analytic theories of optical tuning and injection locking are presented. Results from a comprehensive large signal computer model of the optically controlled IMPATT oscillator are given, illustrating the importance of the composition of the optically generated current on the optical control performance and demonstrating the capability of optical control for rapid frequency tuning. Finally, recent experimental work on optical tuning effects in W-Band IMPATT oscillators is presented.
