Lesson 6 – Second Order Nonlinearity

OptiFDTD provides four types of nonlinear materials. 2nd Order 3rd Order Kerr-effect Raman-effect All of these nonlinearities can be combined with the Lorentz dispersive model, which leads to dispersive nonlinear properties. To simulate the nonlinear material correctly, we recommend that you read the FDTD Basics. Note: Because the nonlinear material may have a high frequency…
