# Electromagnetic, Optics and Photonics This page includes contents from multiple courses and a huge range of different topics. Including nano photonics, crystal optics in intense light field (aka nonlinear photonics and second harmonic generation), nonlinear photonics, and possibly quantum optics. ## Nonlinear optics For nonlinear optics, my current interest is covered in Chapter 1, 2, 3, 6 in Boyd's book [[Nonlinear Optics]]. Namely Maxwell and wave equation description of 2nd and 3rd order nonlinear process, and quantum description. >[!Notice] >We adopt the notation used in [[Nonlinear Optics]] (Page 1), the $\tilde{}$ denotes a quantity varies rapidly **in time**. Constant quantities, slowly varying quantities, and Fourier amplitudes (with time) are written without the tilde. 1. [[Introduction to polarization]] 2.
