Title: Controlling chaos in semiconductor laser devices
Author: Gavrielides, Athanasios; Kovanis, Vassilios; Alsing, Paul
Abstract: In most encounters, chaos is considered a nuisance, if not a downright detriment to system performance, especially in laser devices. However, the presence of chaos in a system can act as a rich source of complex frequencies if one only had a way of accessing them. In this work we present a discussion of the recent work of Ott, Grebogi and Yorke on controlling chaos as applied to a semiconductor diode laser subject to optical feedback via an external mirror. In the regime in which the laser is chaotic, stabilization can be achieved by sampling the output intensity and feeding back minuscule amounts of a correcting signal on the pumping current at the appropriate time interval. We present the results of our numerical investigations.
