Summary:
This study investigates an all-optical microwave generation scheme using a semiconductor laser operating at period-one nonlinear dynamics. In particular, a novel all-optical stabilization approach based on highly asymmetric mutual injection is introduced to improve the phase quality of such generated microwaves. As a result, microwave generation at 55 GHz with a side-peak suppression ratio above 45 dB and a 3-dB linewidth below 3.6 kHz is generated. The stabilized microwave generation across the entire V-band (40-75 GHz) and W-band (75-110 GHz) can be achieved by tuning the frequency and power of optical injection using our proposed scheme.
