"Description of photonic device configurations used in telecommunications systems with an emphasis on technology:Theory and operational properties of individual components and their impact on the transmission and distortion of optical signals: dispersion and nonlinearity phenomena and techniques for their compensation. Integration of photonic components in optical transmission lines. Passive components: single-mode, multi-mode fibers, and polarization-maintaining fibers; optical couplers, optical isolators, and optical filters. Active components: semiconductor lasers, optical amplifiers, optical modulators, and detectors. Introduction to fundamental topics in optical fiber transmission, time-division multiplexing (TDM), wavelength-division multiplexing (WDM), optical logic, and signal processing at ultra-high speeds. The course is complemented by a series of exercises on topics such as optical beam coupling into waveguides, loss characterization, modulation, detection, demodulation, and error measurement, and finally, implementation aspects of transmission systems utilizing quantum optics.”
