Course Overview
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 principal 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. The course is also useful to the junior PhD students and M-Tech students whose research interest is related to Photonics. The exam of this course will be based on multiple choice questions and each week the descriptive type practice-assignments will be given to the students as home work. INTENDED AUDIENCE : 3rd year B. Sc Physics , M. Sc Physics , M-Tech (Applied PREREQUISITES : Basic calculus, Algebra, Basic complex numbers, Basic concept of electrodynamicsINDUSTRIES SUPPORT : None
