The Lightwave Technology Lab (LTL) is focussed on experiments involving optical wireless communication and guided wave optical communication. The current research work includes novel optical communication paradigms targeting 5G and beyond communications such as passive optical networks links, radio over fiber (RoF), radio over free space optics (RoFSO) with orbital angular momentum (OAM) generation, modulation, transmission and detection. Moreover, the lab is also being used for modelling waveguide based passive structures for their applications in passive optical networks. The research work in the lab will also be expanded to include experiments to study nonlinear effects in optical fibers, particularly targeting the issues in high-speed optical communications.
