Capacity of 5G mobile communications might will soon be reached. Among many proposed disruptive technologies in 6G, microwave photonics is one. As mm wave link is proposed in 6G cellular communication, use of Photonic Techniques is emphasized to improve the performance of conventional microwave/millimeter wave wireless systems. 

My research here deals with proposing different architectures for MW & MMW Generation, reception & transmission (with novel photonic devices) via analog Radio over Fiber systems and try to investigate the effects of various fiber nonlinear impairments on the system. I also try to develop architecture for photonic based RF transceiver in GHz and SubTHz frequencies. Designing architectures for Photonic upconvter or so called photonic multiplier is another area of my interers.
