Pulsation regimes near static borders of optically injected semiconductor lasers

Abstract

The semiconductor laser injected externally by another laser (master-slave configuration) is a theoretical and experimental tool suitable for the scientific exploration of non-linear effects. Using numerical tools we have found pulsation regimes aside from period 1 and period 2. Techniques such as finding the maximum and minima of a temporal series, ratio between maxima and minima and the total harmonic distortion can be very useful to find and characterize pulsation regimes. Pulsation regimes where found near the borders of the stable synchronization region of the laser. The characterized region has a range of frequency from 150MHz to 2.78GHz with a frequency detuning from 0.98GHz to 3GHz.
