Abstract

An experimental analysis of phenomena observed in the laser emission of a semiconductor laser operating with an external cavity system in the low-frequency fluctuations regime has been carried out. The chaotic behaviour of the semiconductor laser emission with external feedback is influenced by laser parameters. The optical feedback coefficient, the injection current and diode temperature greatly influence the chaotic system evolution. In this paper we present data about the control of the chaotic dynamics of semiconductor lasers for different sets of experimental parameters..
