Abstract :
The authors show that the coherence collapse instability induced by an external cavity is the origin of the previously reported chaos for laser diodes with delayed feedback. This demonstration opens the question as to whether the observed behaviour is an example of optical chaos or rather is a noise driven instability. Methods are suggested by which the issue can be ultimately decided.
