Abstract

The spectrum features of the external light phase of a semiconductor laser without optical feedback and with optical feedback are analysed based on the Lang-Kobayashi equations, which contributes to putting forward the measurement algorithm of feedback strength factor of optical feedback self-mixing interferometry systems in the frequency domain. The hardware models of this algorithm are established by applying XILINX System Generator tools on the Matlab/Simulink software platform. Finally, the associated simulations for verification of the measurement algorithm in different feedback levels are carried out and it is proved effectively.
