Paper Abstract

New approaches for multiplexing self-mixing interference (SMI) in fiber ring laser (FRLs) are presented. The expression of output powers with optical feedback in FRL with parallel dual-channel and multi-channel is analyzed. The gain competition, the intensity alternation among different channels and the attainable performance are discussed. The experimental results show good agreement with the theory. Therefore, two-channel and multi-channel sensing or measurement will be realized simultaneously.
