摘要
计算机模拟表明半导体激光器非理想调频响应对反馈网络低频截止频率f_c的限制,阻碍提高线宽压窄率.半经典理论分析表明,用双电极非均匀线宽展览因子半导体激光器不仅能压窄谱线而且可以取消对f_c的限制,大大提高线宽压窄率.本文提出了电负反馈半导体激光器的改进方案.
Computer simulation shows that the rate of linewidth narrowing is limited by the low cutoff frequency (fc) of feedback loop, because of the FM response of usuall semiconductor laser. Somiclagsical theory analysis shows that not only the narrowed linewidth output can be obtained, but also the limits to fc can be canceled by using two-electrode imhomogenous linewidth enhancement factor semiconductor laser. In this paper we present proposals for improvement.
