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
entanglement assisted communication and soliton & 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.
