Dr. Laxmi Narayan Tripathi is an assistant professor in Vellore institute of technology Vellore, Tamillnadu. He received Ph.D. in Physics from the Indian Institute of Science, Bangalore, India working with Professor Jaydeep Basu. During Ph.D. he studied exciton-plasmon coupling in the hybrid monolayer of CdSe Quantum dots (QDs) and Au nanostructures like Au nanoparticles, rods known as plasmonic nanoantennas. Using the plasmonic nano-antennas, he had shown controlled photoluminescence enhancement and quenching at varying distances (1-10) nm between the QDs and Au nanoantennas, both experimentally and using finite-difference time-domain simulations. In his post-doctoral studies at Seoul National University, Seoul, South Korea, working with Professor Dai-Sik Kim, he fabricated Silver-QDs-Silver nanogap terahertz ring resonators through innovative self-assembly lithography and measured terahertz field enhancement for biosensing applications. At the University of Würzburg, Würzburg, Germany, working with Dr. Christian Schneider and Professor Sven Höfling, he created deterministic sources of single photons at the site of plasmonic nanostructures, like nanocones, nanopillars and characterized single-photon emission from strained WSe2 monolayers using quantum optical spectroscopy at 4.2 K. His current research interests include quantum-optical spectroscopy of two-dimensional materials on a chip, deterministic single-photon generation from the two-dimensional materials at room temperature and quantum information processing using the single photons on a plasmonic platform. He has also served as reviewers for journals like nature communication, applied physics letters, optics letters, Journal of Raman Spectroscopy, etc. He also holds a Guest Editor position in Journal of Visualized Experiments (JoVE). He has taught several elective courses on photonics like LASER physics and applications, quantum and nonlinear optics, and fiber and integrated optics at Birla institute of technology, Mesra Ranchi, jharkhand, India.
