Abstract :
A method for locking impatt oscillators by illuminating the impatt diode with a low-power laser beam, amplitude modulated at microwave frequency, is described. A large-signal theory of impatt operation, including the effects of finite reverse saturation currents and their modulation by the laser beam, is presented and predicts locking ranges of several tens of MHz with laser powers of a few mW
