MIC634 Generation and Propagation of Light

Instructor: Dr. Anatoly Khilo
Next time offered:  Fall 2013


Brief description:

The course discusses propagation of optical beams in free space, optical systems, and optical fibers, as well as generation of optical beams in lasers and optical resonators. The topics include: diffraction; Fourier optics; basic optical elements and systems (lenses, microscopes, diffraction gratings); Gaussian beams; Fabry-Perot interferometers; optical resonators; basics of light-matter interaction; principles of lasers; laser types; optical fibers; dispersion and nonlinearities in optical fibers; fiber amplifiers; fiber transmission systems.
