Simulation of optically injection-locked microwave oscillators using a novel SPICE model
Abstract
Optical injection-locking of GaAs field-effect transistor microwave oscillators has been examined experimentally as well as by using two different optical interaction models. An additional simulation program with IC emphasis (SPICE) circuit for observing small locking ranges is also described. This first-order interaction model which utilizes a standard version of SPICE produces predictions of injection-locking range in excellent agreement with measured results. These tools allow the oscillator designer to optimize the injection-locking performance by analyzing various circuit topologies and dc bias levels.
