Control of a Chaotic Semiconductor Laser via Modulating Photocurrent

Abstract:

A novel chaos-control method of laser is presented by performing a path of photoelectric delayed nonlinear feedback. Two chaos-control models of injected semiconductor laser are studied by modulating the nonlinear and linear photoelectric delayed controllers. Firstly, by periodic modulation of the linear photocurrent under the condition of nonlinear control, the laser behavior can be brought into a dual-period, or multi-periodic state. Secondly, dynamical chaos-control is achieved successfully by switching the controllers.
