摘要：
The present paper describes the mode conversion of the optical signal using single waveguide coupled silicon micro-ring resonator (MRR). The mode conversion occurs between quasi-TM and the quasi-TE mode at the through port output with the application of the suitable optical pump power. The modeling of mode-conversion using ring resonator is performed through MATLAB as well as by finite-difference-time-domain (FDTD) simulation and further used to perform the all-optical switch. The refractive index contrast, height to width ratio of the waveguide and the choice of suitable wavelength and power for optical pumping and source are responsible for mode-conversion in the ring resonator. The application of mode-conversion to design all-optical switch in MRR is also included in the paper. Mode-conversion in terms of electric field intensity at a resonant wavelength of around 1.53m occurs and is utilized to design all-optical switch. The results obtained from both MATLAB and FDTD justify each other and validate the proposed concept. Some Figure of merits' and Spectral parameters' are calculated in the report to analyze the performance of the design.
