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 Q_factor 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.
