Abstract

This study experimentally investigates the synchronization of chaos produced by semiconductor lasers in a cascade injection configuration. A tunable master laser induces chaos through optical injection into a transmitter laser, which subsequently injects light into a receiver laser. Synchronization between the transmitter and receiver lasers is achieved with a correlation coefficient of 90% over a measurement bandwidth of 35 GHz. Two distinct parameter regions exhibiting robust synchronization are identified, characterized by alignment of the receiver laser’s oscillation frequency with either the transmitter laser or the master laser frequency. Additionally, our experimental setup allows for the generation of two distinct chaos regimes, with correlation coefficients exceeding 90% for each.
