About
I am currently working as Associate Professor in the School of Physics at the University of Hyderabad.
Quantum Photonics Laboratory focuses on exploring fundamental and applied aspects of light-matter interactions using sub-wavelength diameter silica fibers, known as optical nanofibers. These platforms provide strong optical confinement and enhanced evanescent fields, enabling efficient coupling between photons and atoms, quantum emitters, and nanoscale systems. Our research aims to develop scalable photonic interfaces for next-generation quantum technologies. Our group works at the intersection of quantum optics, nano-photonics, and fiber-based quantum systems. We investigate quantum light generation, fiber-integrated quantum devices, atom-photon interactions near nanostructures, and compact architectures. The long-term goal is to develop robust, fiber-compatible quantum photonic platforms suitable for real-world deployment.
The laboratory has been established with funding support from multiple national agencies including SERB, MHRD, CSIR, MoE, and UGC. The facility is designed to support advanced experimental research in quantum photonics, including optical nanofiber fabrication, quantum light characterization, and fiber-integrated quantum device development. Our research is aligned with the rapidly evolving quantum technology landscape, including photonic interfaces for quantum computing. By combining fundamental science with engineering-oriented approaches, the group aims to contribute to scalable and commercially viable quantum photonic technologies.
