Research Interests

Our research focus on discovering novel cost-effective method of fabrication of functional devices which can be deployed over large areas and fabricated on unconventional substrates. To this end, we rely on two strategies-

(1) based on simple nano-imprinting technique to fabricate textured structures followed by thin film deposition to realize planar 2d multi-material and active metasurfaces for electronic and photonic applications.

(2) the other using conventional thermal drawing techniques to realize hybrid or multi-material fibers with a wide range of functionalities.

We do study fundamental physical and material aspects for fabrication of such devices and their physical properties, however at the heart we are interested to develop novel products which are industrially viable, economically important and socially responsible for energy harvesting, sensing, health care and smart fabrics.

Biographical Sketch

Tapajyoti Das Gupta obtained his BSc and Btech in Physics and Radio physics respectively from University of Calcutta in 2006 and 2009. He then moved to France where he obtained his MSc in nanoscience from École Polytechnique (l’X) in 2012 and PhD in Condensed Matter Physics lab (PMC) from the same institute in 2015 under Prof. Thierry GACOIN and Alistair ROWE. He then joined prof. Fabien Sorin’s lab of Fiber Optics and Photonics Devices (FIMAP) in École Polytechnique Fédérale de Lausanne (EPFL) during 2015 December-2019 November. He also served in the Electrical Engineering department in Indian Institute of Technology, Kanpur (IITK) for five months from January 2020 to May 2020, before joining the Department of Instrumentation and Applied Physics in July 2020.
