Bragg Fibers

Ritesh K. Chourasia earned his Master's in Physics (Specialization: Electronics) and Ph.D. from the Institute of Science, Banaras Hindu University (Varanasi, India). His doctoral research work was on Bragg fiber's mathematical modeling, simulation, and exploration of their optical properties in various applications. He qualified for the highly competitive exam CSIR-JRF (Junior Research Fellow) in Physical Sciences to obtain a national fellowship for his Ph.D. and eligibility required for permanent faculty in India. He has also qualified for UGC-NET in Electronic Sciences, an international examination GATE-Physics, and JEST-Physics. He joined as Assistant Professor (Permanent) at Lalit Narayan Mithila University, Darbhanga-846004, in 2017, and presently he is working as Head, Post-Graduate Department of Physics, Samastipur College, Samastipur-848134 (A Constituent College of L.N. Mithila University, Darbhanga, 846004). He has published numerous quality research papers, review articles, and book chapters in international journals and publishers of repute.  He has also two granted Indian patents on Bragg fibers. He is currently supervising four Ph.D. students and also has supervised numerous Master's dissertations. He has also served as guest editor and is involved in the Editorial board of many indexed journals. Currently, his prime research interest is non-linear aspects of Bragg fibers, Bragg fiber gratings, and photonic crystals.

Aavishkar Katti earned his Bachelor's and Master's degrees in Physics with a specialization in optics and spectroscopy from the University of Delhi (Delhi, India). He then completed his Ph.D. from the Banaras Hindu University (Varanasi, India). His doctoral research work was on optical solitons in nonlinear optical materials. He has qualified for the intensely competitive National Eligibility Test required for a teaching position in India. He has been associated with Banasthali Vidyapith and now MIT World Peace University as Assistant Professor of Physics. His areas of interest include nonlinear optics and nonlinear dynamics. He has published in many reputed and indexed journals and has a track record of robust independent research. He has supervised many Masters's and Doctoral students. He has published a research monograph on Optical Solitons previously while he also has edited books to his credit. He has served as guest editor and is on editorial board of reputed and indexed journals. In recognition of his research, he has been awarded with research grants from the Govt. of India, including the prestigious Core Research Grant.
