Paper Abstract

Feeding light inside a semiconductor laser gives rise to a wealthy set of dynamics that have been largely described. The two fundamental parameters are the detuning and the injected power. We present here theoretical and experimental evidence that other parameters may play a role. For instance, injecting with an orthogonal polarization is not equivalent to nullify the effect of optical injection as demonstrated by our experimental map. We will focus the main part of the talk on the influence of coherence. Some part of this study has been made possible by the use of a single-frequency fibre laser which enables us to establish an enlightening comparison between these two different types of lasers and also to surround the influence of coherence.
