Abstract

We study the dynamics of semiconductor lasers subject to strong delayed optical feedback. We find that the discrete nature of the external-cavity modes leads to a discrete set of relaxation oscillation frequencies observed at the onset of the first instability as the pump current is increased. This explains experimentally observed hops between the frequencies.
