Researcher: Krishna Kumar

Researcher CV: Krishna Kumar completed his Master of Science (Five Year Integrated) in Photonics from International School of Photonics, Cochin University of Science and Technology (CUSAT), India, (2014 – 2019).  He did his master’s thesis at Raja Ramanna Centre for Advanced Technology (RRCAT), Indore, a unit of Department of Atomic Energy, Government of India on a topic entitled “Development of pulsed dye laser pumped by Nd YAG laser for Spectroscopic applications”. During 10/2019 – 06/2020, he worked as a scientific researcher at Department of Chemistry, University of Helsinki, Finland on “Mid-Infrared Laser” particularly focused on a project entitled “Development of new mid-infrared frequency comb technology”. He has experience of working in the field of high-power femtosecond frequency comb laser, nonlinear optics, laser-mode locking, laser phase noise measurement and analysis, laser spectroscopic measurements and its data analysis. Recently he joined DAS Photonics, Spain as a MSCA-EARLY-STAGE RESEARCHER and started working on “Photonic systems for THz Spectroscopy and imaging”. 

Objectives: This research is aimed at developing new methods and processes for THz sensing platforms based on the quasi time domain spectroscopy (QTDS) for applications in material sciences such as THz scattering spectroscopy

Expected Results: This research activity is aimed at developing an optically-mediated multi-frequency and beam-steerable THz source tool to expand the application field of THz Photonics to material sciences and spectroscopy. Work in this activity will contribute to the expansion of non-destructive material testing for material characterization and identification in the THz domain as well as for THz imaging. This research work will contribute to answering TERAOPTICS’ research Challenges II, III and V.

Planned secondment(s):
to FTMC (Prof. Gintaras Valušis), M10 ~1 month, on introduction into diffractive optics for THz frequency range
to UC3M (Prof. Guillermo Carpintero), M24 for ~ 1 month, for THz imaging experiments
to UDE (Prof Andreas Stöhr), M30 for ~ 2 month, for THz imaging and QTDS experiments
