Abstract

In this paper, we show that a coupled diode-injection laser stripe array system with complex coupling coefficients can be stabilized around the lowest order supermode using a feedback-control law and verify the system performance by numerical simulations. The symmetry of the array can be exploited to obtain a feedback-control law of a particularly simple form.< >
