Paper Abstract

This study analyzes phase mismatching values of guided-modes in a multimode waveguide with a weak-guiding configuration. In addition, a previously undefined self-imaging phenomenon, referred to herein as the extraneous self-imaging (Ex_SI) phenomenon, was found to result from the modal phase mismatching effect. The evolution principle of the Ex_SI phenomenon is theoretically verified, while the results from the numerical method are compared with graphical and analytical forms of the newly suggested method. Moreover, under a specific condition, the numerical results and the analytical results are compared to analyze the evolution of the Ex_SI phenomenon.
