Paper Abstract

In this manuscript we analyze experimentally the noise effects on the modal dynamics of semiconductor lasers. Modal switching is the dominant feature of multimode semiconductor lasers. In bulk lasers, two modes coexisting for the same values of the parameters switch under the action of the noise present into the system (mode-hopping). In this kind of laser we give evidence of stochastic resonance of the mode-hopping under modulation of the laser pump. In quantum-well lasers the modal dynamics is radically different: it consists of a periodic switching among several longitudinal modes, following a well determined sequence from the bluest to the reddest mode in the optical spectrum. The switching dynamics of the modes obeys to a perfect antiphase leading to an almost constant total intensity output.
