6. Optical Phase Conjugation and All-Optical Demultiplexing using Four-Wave Mixing in Dispersion Shifted Fibers
Abstract : This thesis deals with two applications of four-wave mixing in optical dispersion-shifted fibers; optical phase conjugation and all-optical switching. The work is a part of an effort to study the upgradability of the existing fiber plant, which is of large economic interest. READ MORE

9. Modulation Optimization for Noncoherent Optical Systems
Abstract : There has been a significant improvement in high-speed electronics and optical components over the past few years, and this is one of the key enabling factors for high data rate transmission. Moreover, multi- level modulation formats, which encode information onto the carrier’s amplitude and phase, are necessary to increase the spectral efficiency of communication systems. READ MORE
