Welcome
The Photonics Research Group was formed in the department of Electronics and Electrical Engineering, Indian Institute of Technology Guwahati in 2015. The laboratory has been involved in a wide range of research areas such as Silicon Photonics, Photonic Integrated Circuits, Optoelectronics Devices, III-V compound semiconductors, Microelectronics and Device Characterisation, Group IV photonics, Fiber-optic Sensors, Optical devices for health monitoring, etc. We are currently focusing on the research topics which involve Optical Modulators, Hybrid Multiplexers for Optical Interconnects, Thulium Doped Fiber Amplifiers, Vacuum Electron Devices, Photonic Sensors, Distributed Acoustic Sensing, Antennas and DRA design for 5G and beyond applications, etc. We welcome research project collaborations with the industry and academia to develop technology solutions for various photonics applications.
