Abstract

Injection locking is a way of sinchronizing one free-running oscillator to a stabilized master oscillator. When considering applications utilizing this technique in semiconductor lasers, the noise properties of the locked lasers are of vital importance. In this paper we present and analyze some clarifying simulation results about determinate aspects related to the effect of noise on injection-locking. In this aim, a new semiconductor injection-locked laser modelling technique that includes this important effect of noise, both from the injected laser and from the external source, has been implemented. This modelling technique is based on a description of the coherent rate equations in terms of a funcional blocks diagram that can be analized by means of a suitable computer simulation program
