Description

Physics of Linear and Nonlinear Optical Waveguides. Instructor: Prof. Samudra Roy, Department of Physics, IIT Kharagpur. Optical waveguide is a physical structure that guides electromagnetic waves and it is the most important component of integrated optical circuits.

This course is intended to describe the theoretical basis of optical waveguides. In this course we learn the principle of light guidance by understanding the light-matter interaction in linear and nonlinear regime. We will also discuss different optical components based on waveguides that are used extensively in communication and sensing. This course is mostly self-contained with very basic prerequisites like knowledge of elementary algebra and calculus. The course is prepared for the senior graduate and M.Sc. students having a prior knowledge of electromagnetic theory. (from nptel.ac.in)
