In the coming days, free space optical communication could play a key role in indoor and outdoor applications, especially in the defense sector.

The Guwahati Institute of Technology, India, has completed the technology transfer (ToT) of a new free-space optical communication system to the telecommunications industry.

The advanced communication system uses wavefront modulated light beams for wireless error-free data transmission through free space rather than through optical fiber,” according to a press release.

The technique was developed by prof. Bosanta Ranjan Boruah, Department of Physics, IIT Guwahati, and Santanu Konwar, Assistant Professor, Department of Physics, Abayapuri College, Assam

This technology has obtained a US patent dated June 2, 2020, a Japanese patent dated December 23, 2021, and a Korean patent dated December 28, 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 defense sector. We will be looking forward to meeting the challenges as our technology is adapted to serve society,” said Prof. Bosanta Ranjan Boruah, Department of Physics, IIT Guwahati.

The research team experimentally demonstrated the distortion-free transmission of text messages and images in a laboratory environment, even in the presence of turbulent flow, as well as outside the laboratory. Thus, the communication system can be used for high-speed and secure communication between two remote sites in line of sight, with virtually no possibility of unauthorized interception.
