IIT Guwahati transfers novel 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 advanced communication system uses wavefront modulated light beams for wireless error-free data transmission through free space rather than through optical fibre,” said a media release. 

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

It is worth mentioning that the technology has been granted with US patent dated June 2, 2020, a Japanese patent dated 23 December, 2021, and Korean patent dated 28 December, 2022. 

“Free space optical communication is likely to play a crucial role in the coming days both in case of indoor applications and outdoor especially in the defence sector. We will be looking forward to meet the challenges as our technology is adapted to serve the society,” said Prof. Bosanta Ranjan Boruah, Department of Physics, IIT Guwahati. 

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.
