Abstract
Based on the period-one nonlinear dynamical state of an optically injected semiconductor laser, an all-optical method for photonic microwave generation is proposed and investigated experimentally. Experimental results show that through jointly adjusting injected optical strength and frequency detuning between the injected light and the solitary laser, a photonic microwave signal with a tunable frequency range of several tens GHz can be acquired. Via by introducing an optical feedback and properly selecting the feedback strength, the linewidth of photonic microwave can be narrowed about two orders of magnitude.
