This project aims to develop a high performance solution for the challenging problem of measuring the linewidth enhancement factor (LEF) of semiconductor lasers (SLs) and the optical feedback level factor, C, for the optical feedback self-mixing (OFSM) systems. Specific outcomes of the research include (1) a new model for an optical feedback self-mixing effect, (2) a new approach for measuring LEF and C based on the proposed model, (3) signal processing algorithms for improving the performance of the proposed approach, and (4) an OFSM system prototype based on the new model and algorithms.
