THz communication technology in India: Present and future

As the communication industry is currently undergoing a major overhaul to accommodate greater bandwidth and higher data-rate to meet the rapidly growing data demand; terahertz range of frequencies from 100 GHz to 3 THz are being investigated as a possible replacement of the conventional mm-wave technology. In this paper, the technological readiness of Indian research community in this specific direction have been examined. The research development strategies that are required to gain momentum towards achieving a viable technology standard in THz communication in India are discussed. Technology recommendations towards product development required for initiation and advancement in THz communication are presented. We have also introduced a design of a short-range THz communication configuration in conclusion, based on recent reports of successful realisation of THz communication which could be utilised for immediate realisation using commercially available resources.
