This course introduces fundamental principles of fiber-optic communication systems within the context of applications for access, metropolitan and long-haul networks. Topics include distributed feedback semiconductor lasers, optical modulators, planar dielectric waveguides, propagation characteristics of single-mode optical fibers, p-i-n and avalanche photodiodes, and digital receiver performance. Device technology and system design applications are considered.
