Hi, I design a Silicon waveguide. I have calculated the modes (effective index, loss) for different wavelength. Now I want to give two input, one is the signal wavelength and the other one is the pump wavelength at the one end of the waveguide. Because of the kai(3) process, it will produce an idler wavelength (Degenerated four-wave mixing process). How to simulate this process in Comsol, especially how to give two input in Comsol and how to write the polarization P as a function of the electric field of pump and signal.
