Switching On/Off of Cavity Solitons in Semiconductor Microresonators via Carrier Injection above Laser Threshold abstract
We studied the Cavity Solitons (CSs) and their switching in a semiconductor Fabry-perot type microresonator where the active medium is GaAlAs/GaAsmultiple quantum well nano-structures. We take benefit of the full set of Maxwell-Bloch equations to describe the dynamical behavior of the system, since the rate equation model for a two-level system fails to explain the system when consideringfemto-second time scales. Numerical simulations imply formation of stable CSs which is done by local carrier injection as the switching method. To switch off these CSs we used the same method but with negative amplitude of the injection function. It is also realized that the successive switching on/off of CSs by such a scheme is possible in this system. Switching by this method has some advantages over the coherent switching, either in switching on or in switching off process.
