Abstract
This study investigates an all-optical microwave generation approach using a semiconductor laser operating at period-one nonlinear dynamics. In particular, a novel all-optical stabilization scheme based on highly asymmetric mutual injection is proposed to improve the spectral purity of such generated microwaves. As a result, microwaves at a frequency of 64.3 GHz with a 3-dB linewidth below 2.7 kHz and a SPSR of 46 dB is generated. Microwave generation with high spectral purity over the V (40 to 75 GHz) and W (75 to 110 GHz) bands can be achieved by simply adjusting the power and frequency of optical injection.
