Module IV: Photo Detectors

Characteristics of photo detector, direct and indirect band gap semiconductors, homo junction and hetro junction

photodiodes, p-i-n photodiode, avalanche photodiode, phototransistor, optocouplers.

Module V: Fiber Optic Communication System

Basic communication components, coupling to and from the fiber, multiplexing and coding, repeaters, bandwidth

and rise time budgets, noise, bit error rate and eye pattern.

Module VI: Optical Networks

Network Topologies, SONET/SDH, Optical switching, WDM systems, Fiber optic sensors.
