Web11 Nov 2024 · Hello, This code solves the nonlinear in optical communication but, it only plots the time domain, I need to plot that frequency domain as well for both 3D and 2D plot. Thank you for help if... To a complex electric field corresponds an intensity and an intensity autocorrelation function defined by The optical implementation of the intensity autocorrelation is not as straightforward as for the field autocorrelation. Similarly to the previous setup, two parallel beams with a variable delay are generated, then focused into a sec…
