Research Scholar at Indian Institute of Technology Delhi, India
Dr. Ajay Kumar is a physicist specializing in Computational Photonics, with expertise in MATLAB, COMSOL, Rsoft, and Lumerical. He received his Ph.D. in Physics from the Department of Physics, Indian Institute of Technology (IIT) Delhi on 02 July 2025. His doctoral thesis, titled “Modelling and Analysis of Higher Order Modes in Optical Fibers & Components”, was carried out under the supervision of Prof. Anurag Sharma (NASI Distinguished Chair Professor, IIT Delhi), with Prof. R. K. Varshney (IIT Delhi) as co-supervisor. Prior to his Ph.D., he earned his M.Sc. in Physics (2017) from Kurukshetra University and his B.Sc. in Physics, Chemistry, and Mathematics from Govt. College Hisar, Kurukshetra University. During his academic journey, Dr. Kumar has been recognized with several prestigious fellowships and awards. He was a recipient of the Early Doctoral Fellowship (EDF719-MI02585G) under IoE Promotional Measures, IIT Delhi (2025). He secured the SERB-ITS International Travel Grant to attend FiO-LS 2024, and the Research Scholar Travel Award (2023) from IIT Delhi for participation in OWTNM 2023, Marseille, France. His research contributions have also been acknowledged with the Best Oral Presentation Award at ICEMQP-2024 (Guru Jambheshwar University, Hisar) for his work on Modal Analysis of Higher Order Modes in Ring Core Fibers, and the Best Poster Award at PHOTONICS-2023, IISc Bangalore for A New Method for Obtaining Loss in Leaky Fiber Structures. He qualified multiple national-level examinations, including CSIR-NET JRF/SRF (2017), JEST (2017), and GATE (2022). Earlier in his career, he was awarded the Dr. B. R. Ambedkar Scholarship and the National Merit-cum-Means Scholarship by the Department of Higher Education, Haryana. His research primarily focuses on the modal properties of advanced fiber structures, leaky modes, and higher-order mode analysis, contributing significantly to the development of photonic devices and components. To date, he has authored [X] peer-reviewed publications, which have collectively received [Y] citations, with an h-index of [Z] (as per Google Scholar/Scopus). Dr. Ajay Kumar continues to advance research in computational modeling of optical fibers and photonic devices, with a vision to bridge theory and practical applications in next-generation optical communication technologies.
