Summary

This article presents a numerical study of a nonlinear optical loop mirror (NOLM) using Jones matrices and 3D plots to analyze how parameters like fiber loop length, input power, QWR angle, and input polarization affect its performance. The research investigates both linear and circular input polarizations and their influence on switching power and dynamic range. The findings demonstrate that adjusting the QWR for circular polarization and the HWR for linear polarization allows for greater control over NOLM operating conditions, which is crucial for applications such as ultrafast pulse generation in figure-eight lasers (F8Ls) where the NOLM can function as a saturable absorber (SA). The 3D visualizations provide a detailed understanding of the NOLM's transmission characteristics to determine optimal high- and low-power operation.
