Abstract
The traditional Fabry–Perot (FP) method is widely used to measure propagation loss, which is a critical parameter in characterizing the performance of optical waveguides. This work probes the significant influence coming from the multiple resonators coupling (MRC) effect on the performance of the FP method. This letter presents a theoretical analysis and simulation of the MRC effect that are in good agreement with experimental results. This letter verifies that the MRC effect will introduce a varying envelope to the transmission spectrum, stating its challenge to the operational bandwidth and reliability of the FP method. In addition, this letter experimentally demonstrates an effective route to suppress the MRC effect by optimizing the reflectivity of the fiber end-facets, which verifies the scalability of our theoretical model and has strong practical application value.
