18-819D: Special Topics in Applied Physics: Nonlinear Optics and Photonics
Nonlinear optics plays an indispensable role in modern photonics and is the driving force behind many important applications, such as frequency mixing in the classical domain and entangled photon sources in the quantum domain. This class aims to develop a systematic treatment of nonlinear light-matter interactions from the perspectives of both classical Maxwell’s equations and quantum optics. First, by introducing nonlinear susceptibility to classical EM wave equations, we will study two key concepts of nonlinear optics: phase matching and energy conservation, in the context of various second- or third-order nonlinear processes. Second, we will also cover the basics of quantum optics relevant to this course, which will help reveal the fundamental origins of nonlinear susceptibility and allow us to treat light-matter interactions in the quantum regime. Quantum applications such as spontaneous four-wave mixing, spontaneous parametric downconversion, and quantum frequency conversion will be discussed.
