Abstract

We demonstrate for the first time a nonlinear finite-difference time-domain (FDTD) analysis of optical parametric four-wave mixing (FWM) in an actual InGaAsP-InP-based racetrack microresonator, and the results are compared with measurements on an experimental prototype. It has been found from the two-dimensional (2-D) and three-dimensional FDTD analyses that the resonance frequencies can be reasonably predicted by an FDTD model by considering the strong material dispersion of the waveguide medium and that the wavelength conversion by FWM is not sensitive to the dimensionality of the model; thus, it is efficiently predicted by the 2-D FDTD model.
