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.

利用半导体激光器在高度不对称相互注入下的一周期非线性动力学产生光子微波
本文研究了一种利用半导体激光器工作在一周期非线性动力学下的全光微波产生方法。特别地,提出了一种基于高度不对称相互注入的全光稳定方案,以提高所产生微波的光谱纯度。结果,产生频率为64.3 GHz、线宽为3db、SPSR为46 dB的微波,线宽低于2.7 kHz。在V (40 ~ 75 GHz)和W (75 ~ 110 GHz)频段产生高光谱纯度的微波,只需调整光注入的功率和频率即可实现。
