Abstract
The immense potential of metasurfaces is showcased by demonstrating several applications with plasmonic metasurfaces along with their polarization response using Mueller matrix spectroscopy. The work on plasmonic metalenses and holograms with an arbitrary composition of the AuAg alloys shows the successfully fabricated complex nanostructures only by heating nanostructures with a bilayer of Au and Ag of varying thickness at a low temperature of 300°C that retain the shape perfectly. In addition, the spin-orbit photonic effects in a waveguided plasmonic crystal after interacting with structured non-paraxial light via leaky mode excitation is imaged using dark-field Mueller matrix imaging.

Debdatta Ray is currently an INSPIRE Faculty Fellow in the Department of Physical Sciences at IISER Kolkata. Prior to this position she was working as a National Post-Doctoral Fellow under Prof. Nirmalya Ghosh at IISER Kolkata and as a post-doctoral fellow under Prof. Cornelia Denz, in the University of Muenster, Germany with the Women in Science (WIRE) Fellowship. She was awarded the Swiss Government Excellence Scholarship to complete her PhD from the Swiss Federal Institute Of Technology, Lausanne (EPFL, Switzerland) under the guidance of Prof. Olivier J.F. Martin. During her PhD she has undertaken investigation and extensive nanofabrication in world-class cleanrooms of several types of optical metasurfaces made with metal, dielectric that were published in several peer-reviewed journals. She was also awarded the IIT Master Sandwich Scholarship by DAAD to work with the University of Stuttgart, Germany on plasmonics while pursuing her M.S (By Research) on Photonics from IIT Madras.
