A PhD dissertation was discussed at the Al-Najaf Technical Engineering College, at Al-Furat Al-Awsat Technical University:

“Developing an Optical Communication System Using Plasmonic All-Optical Flip-Flops and Multiplexers”
(An Approach For Enhancing Optical Communication System With Plasmonic All-Optical Flip-Flops And Multiplexers)

By researcher Wisam Abdul Jasim from the Department of Communication Techniques Engineering.
This dissertation aims to develop advanced plasmonic nano-structures used in building optical logic circuits, contributing to improving the performance of optical communication systems, reducing the size of components, increasing response speed, and enhancing transmission efficiency.

The dissertation achieved:

• High transmission efficiency and an excellent contrast ratio of 25.6 dB in the T flip-flop logic gate and 20.9 dB in the 2×1 MUX multiplexer.
• Reduced design time by relying on artificial intelligence techniques.
• Integration of more than one logical function within a single nanoscale area.
