Influences of Linewidth Enhancement Factor of Semiconductor Laser on Self-Mixing Signal
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.
