IIT Guwahati transfers free-space optical communication technology to telecom industry

Indian Institute of Technology Guwahati has completed the transfer of technology (ToT) of a novel free-space optical communication system to the telecom industry.

The technology has been developed by Prof. Bosanta Ranjan Boruah, Department of Physics, IIT Guwahati, and Dr. Santanu Konwar, Assistant Professor, Department of Physics, Abhayapuri College, Assam.

The technology has been granted with US patent dated June 2, 2020, a Japanese patent dated Dec 23, 2021, and a Korean patent dated Dec 28, 2022.

The research team has experimentally demonstrated the distortion-free transmission of text messages and images in laboratory environment even in the presence of turbulence and also outside the laboratory.

The communication system can thus be used for high-speed and secured communication between two remote sites in the line of sight with virtually no possibility of any unauthorised interception.
