Course Objectives: The objective of the present course is to introduce fundamentals of optical fibers, detectors and amplifiers and their applications in
communication system.
Pre-requisites: Students must have the knowledge of laws and principle of optics, electromagnetic theory, semiconductor materials and devices and
communication system.
Student Learning Outcomes: On completion of this course, the students will be able to demonstrate knowledge of the optical laws and definitions of
Classify fibers as single-mode, multimode, step index, and graded index .From module II, they will understand the hard core theory of modal
analysis and describe modes in multimode fibers and mode field parameter in single-mode fibers. From module III & IV they learn about the
various sources and components of optical fiber communication system.
