ECE/OPTI 632: Advanced Optical Communication Systems

Course Description

Advanced technologies and methods that enhance the overall optical transmission system performance and throughput, and the trade-offs related to the system engineering process. Topics include advanced chromatic dispersion compensation, PMD compensation and the nonlinearity management. The spectral efficiency limits will be described and techniques to achieve it, such as turbo equalization, forward error correction (FEC), and coded modulation. Advanced modulation formats, such as various multilevel modulations and OFDM, and constrained coding techniques suitable to deal with fiber nonlinearities will be presented. Further, the spatial-domain based multiplexing and modulation will be studied. The physics behind parametric amplification will be presented as well as its application to all-optical regeneration, wavelength conversion, and multibanded switching. Other topics include soliton and dispersion-managed soliton transmission.

Each chapter (from course syllabus) will be followed with a comprehensive homework. A semester long project in which students will be able to design a high-speed optical transmission system using the concepts introduced in this course is predicted. 

Grading: Regular grades will be awarded for this course: A B C D E.
