2. 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

3. A Novel Oil-immersed Medium Frequency Transformer for Offshore HVDC Wind Farms
Abstract : In this project, a design of an oil type medium frequency transformer for offshore wind farm applications is proposed. The design is intended for applications when series coupling of the output of the DC/DC converters of the wind turbine on their secondary side is done to achieve a cost-effective high voltage solution for collecting energy from offshore wind parks.
