We discuss experimentally and numerically the dynamical behavior of a novel integrated semiconductor laser subject to multiple optical feedback loops. The laser's structure consists of distributed feedback section coupled to a waveguide, an air gap section and two phase sections. It is found that the laser, due to the multiple feedback loops and under certain operating conditions, displays chaotic...
In this paper, we numerically demonstrate secure data transmission using ldquotwinrdquo semiconductor lasers in which chaotic dynamics and synchronization are achieved by electrical injection into the laser pair of a common, chaotic driving-signal, obtained by photodetection of the emission of a third chaotic laser.
