激光线宽展宽因子对半导体激光自混合信号影响的研究
Influences of Linewidth Enhancement Factor of Semiconductor Laser on Self-Mixing Signal
摘要
采用数值模拟法获得了自混合信号的时域特性,并在此基础上对激光器重要参量线宽展宽因子在混合信号中的影响进行了数值模拟和分析,得出了采用较大线宽展宽因子的激光器可以获得幅度较大以及较强的不对称自混合信号的结论.
Abstract
This paper presents a theoretical analysis on self-mixing interference by using a three-mirror model. The laser self-mixing signal with different values of the linewidth enhancement factor α is obtained by numerical solution Results indicate that adopt semiconductor laser with big values of a can enhance SNR of self-mixing signal and in favor of direction discrimination.
