Photonics research group is an initiative of Electrical Engineering department to promote innovative and sustainable light-based solutions to the existing (local and global) issues. Photonics technologies respond to the needs of humankind by providing access to information, promoting sustainable development, and increasing societal health and well-being. The research group is dedicated to provide next generation technology development in applications across light (photon) generation, detection, and manipulation through emission, transmission, modulation, signal processing, high speed switching, amplification and sensing.               

We are offering exciting research opportunities to young graduates (MSc and PhD) who are willing to contribute in the future Photonics industry.  We currently are in early stage of development and working on the following areas:

1. Single longitudinal mode CW lasers for near to short wave infrared spectral region
2. Novel Modulation Techniques
3. Optical Fibre based Communications
4. Free Space Optical Communications
5. Improved energy harnessing using PV solar cells
6. Visible light communication-based Li-Fi technology
7. Ultrashort pulse generation in novel gain media for medical applications
