Abstract

Semiconductor lasers exhibit a characteristic amplitude-phase coupling, therefore amplitude dynamics is usually associated with dynamics of the optical frequency as well. We exploit this relationship to demonstrate experimentally a semiconductor laser system with two external cavities (two different delay times) that displays a dynamical regime dominated by state-dependent delay dynamics. This particular type of delay dynamics is relevant for many systems, including internet traffic, space communication, control theory, economics, turning processes, deep drilling, predator-prey systems, and blood-flow, and might inspire novel applications.
