Lesson 6 – Second Order Nonlinearity
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…
FBG Fiber Loop Mirror Sensor Design Basics
September 26, 2018
Fiber loop mirror configurations have been used in several different applications. One important application is sensing. Inserting a Fiber Bragg Grating (FBG) in the fiber loop mirror allows exploiting the switching feature of the loop mirror to enable enhanced sensing and accessing capabilities.
