Research Laboratory for Plasmonics

Overview of the Research

Plasmonics – science and technology of confining the free propagating electromagnetic wave into low dimensional systems (nanostructures) – is an important area of nanophotonics. This exciting area of research enables developing high efficiency ultra -thin solar cells, ultra -high sensitive biosensors, plasmonic lenses wherein the light can be focused beating the conventional diffraction limits and quantum plasmonics. We are able to develop highly inexpensive, one step methodology to prepare plasmonic metasurfaces on optically thick metallic (Ag, Au) thin films. Presently we are utilizing these plasmonic metasurfaces to realize ultra- thin solar cells, biosensors and super lenses etc.


Ultra Violet (UV) Plasmonics is another sub-area of research which is highly upcoming in Plasmonics. This UV plasmonics can be realized by developing Al nanostructures. These nanostructurs are having wide applications in bio-sciences through Localised Plasmonic Resonanance (LSPR) and SERS techniques.

Doctoral students :



R M Piragash Kumar


He received his Masters in Physics from Bharathidasan University, Tiruchirappalli, Tamilnadu. He is currently developing a wet-chemical etching based nanofabrication technique to produce large-area plasmonic metasurfaces comprised of random nanopits and random nanoholes. His research is focused on exploring the random plasmonic metasurfaces (RPMS) for applications in plasmonic nanosensors for biomolecular sensing, surface-enhanced Raman spectroscopy (SERS) and plasmonic solar cells.


Research interests: Plasmonics, metasurfaces, nanofabrication, microscopy, UV-Visible spectroscopy, colloidal lithography.
