Shreesha Rao Delanthabettu Shivarama


Shreesha is from Karnataka, India. He received B. Sc (Honours) in Physics in 2012, M. Sc. in Physics (photonics specialization) in 2014 and M. Tech. in optoelectronics and communication (Gold medallist) in 2016 from Sri Sathya Sai Institute of Higher Learning, Prasanthinilayam, India. His M. Sc. thesis was ‘Regularity of the atomic mass surface and the use of trends in the atomic mass surface’. His M. Tech. thesis was ‘Novel fiber optic gyroscope using a ring resonator with reflector’. He later worked as project associate at the department of electrical engineering, IIT Madras, India, on the project ‘Study of underwater laser communication’. His research interests include Ultrafast optics, Fiber optics and Nonlinear optics.

As a part of SUPUVIR project, he joined the Ultrafast infrared and terahertz science group at Technical University of Denmark (Department of Photonics Engineering) in 2017. His Ph. D. at DTU will aim to study supercontinuum generation in novel fibers. The scope of the proposed Ph. D. project is to investigate SC generation (SCG) with mode-locked femtosecond fiber lasers, pumping various fibers in their anomalous dispersion regime. Using femtosecond pumping for supercontinuum generation is attractive because the coherence properties of the supercontinuum are superior compared to pumping with longer pulses, and the fiber-laser technology is the most attractive platform for rugged application-oriented supercontinuum modules. Apart from silica fibers, SCG in novel fibers like soft-glass fibers including fluoride, tellurite, and chalcogenide fibers will also be studied. To this end, speciality fibers from the ITN consortium will be tested for its SCG properties.
