Abstract
Semiconductor laser performances are affected by optical feedback even at low levels. Differences between front and rear facet emission arise from optical feedback. Experimental results are discussed. To implement the usual microscopic approach a first principles calculation of coherence length for the radiation which is emitted by a system (laser device and the optical feedback source) is given, leading to a non equivocal definition of coherent and incoherent feedback, even for single mode systems. A model is built that is naturally prepared for massive parallel computation by suitably shaping microscopic processes into rules of evolution of a Cellular Automation. The results of theoretical investigations give a common framework for the wealth of experimental results otherwise looking contradictory and allow the identification of the relevant parameters.
