About Course
The Optical Waveguides is a physical structure that guides electromagnetic waves and it is the most important component of integrated optical circuits.
This Optical Waveguides 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 the linear and nonlinear regimes. 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 prior knowledge of electromagnetic theory. The course is also useful to the junior Ph.D. students and M-Tech students whose research interest is related to Photonics. T
INTENDED AUDIENCE:3rd year B. Sc Physics, M. Sc Physics, M-Tech (Applied Optics)
