Abstract: The coupled nonlinear Schrödinger (NLS) equations describing power and phase of the optical waves are used to model phase‐sensitive (PS) parametric amplification in a width‐modulated silicon‐on‐insulator (SOI) channel waveguide. Through solving the coupled NLS equations by the split‐step Fourier and Runge‐Kutta integration methods, the numerical results show that the coupled NLS equations can perfectly describe and character the PS amplification process in silicon waveguides.
