Optical switching in dual injection-locked Fabry-Pérot laser diodes: Optical switching by injection power and frequency detuning variation

Theoretical study of switching in a Fabry-Pérot semiconductor laser under dual injection-locking is performed and presented. The investigation is conducted in the range of multistability, in which up to three stable states of the slave laser can exist simultaneously. We numerically investigate slave laser switching time in the process of simultaneous variation of two injection parameters: the master laser injection power (amplitude controlled switching) and frequency detuning (phase controlled switching). By using this switching mechanism, we obtain significant improvement of the slave laser switching time compared to the mechanism comprising just injection power variation.
