Description

Modern Optics. Instructor: Prof. Partha Roy Chaudhuri, Department of Physics, IIT Kharagpur. Optics is a core discipline in science

There has been a remarkable upsurge in Optics in view of technological advancement, rapidly growing applications in the broad area of optics and photonics encompassing all sectors of civil, defense, biomedical research, signal processing and instrumentation. In the proposed course we plan to bring up the basic characteristics of electromagnetic propagation in material media of isotropic/anisotropic linear/nonlinear nature, propagation in layered structures and waveguides. The interaction of light waves with intervening media that gives rise to various phenomena, namely the electro-optic, magneto-optic, acousto-optic effects will be discussed in the platform of the underlying physics. The course will offer a comprehensive background in understanding several device applications based on these light-matter interaction properties. (from nptel.ac.in)
