Course Content (Syllabus)
Evolution of optical communication systems overview. Optical waveguides and optical fibers: characteristics, ray theory and wave theory, guided modes, mode classification. Special types of fibers. Slab waveguides and planar optical waveguides. Transmission in optical fibers: Attenuation mechanisms. Classification of dispersion mechanisms, material dispersion and waveguide dispersion. Transmission equation in single-mode fibers. Transmission of Gaussian pulses when subjected to GVD & TOD, transmission of arbitrary shape pulses, effect of source finite spectral width. Limitation in maximum bit-rate due to dispersion. Light sources: Laser basic principles, light emission in semiconductors, laser diodes (LD), types of LD (Fabry-Perot, Edge Emitting, VCSEL), operation characteristics, modulation. Light Emitting Diodes (LED). Coupling with fibers. Optical detectors: PIN photodiodes and avalanche photodiodes. Direct detection optical receiver: noise sources (thermal, quantum and dark current noise), quantum limit, signal-to-noise ration (SNR), typical receivers, receiver sensitivity, factors that restrict receiver sensitivity. Optical communication systems: basic architectures, design restrictions, multiplexing techniques (Optical Time Division Multiplexing OTDM, Wavelength Division Multiplexing WDM).
