It is based on the injection locking of two distinct semiconductor lasers, that makes possible the generation of high purity beat signals in the microwave frequency range. Such a technique can be used either in the pulsed pump-probe technique or the new correlation-based technique. Furthermore novel devices, such as laser modules presenting integrated electro-absorption modulators, can be exploited for achieving efficient and cost effective injection locking schemesBrillouin spectrafibre optic sensorslaser mode lockingtext::conference output::conference proceedings::conference paper
