Abstract: For modelling the nonlinear effect on the race track structure, the 2D, FDTD has been utilized to overcome the reliability of the results the var-FDTD has been considered using 2.5D algorithm. The nonlinearity effect can be described by χ3 which is cooperating with dispersion value of the material. The parameters have been studied such as Qfactor that is optimized to be 1.68 × 103. The silicon material has been used to compare with nonlinearity-based silicon so that the differences can be more logic. The converted wave has been found to be around 1.508 μm.
