  • Quantitavite detection of tiny polarization anisotopy effects.
  • Natural weak value amplification of magneto-optical effects.
  • Weak measurement using spectral degree of freedom of light.

Nano-optics

  • Basic studies on light-matter interactions at the nano scale.
  • studies on localized surface plasmon resonance in metal nano-structures.
  • Studies on coupled plasmons, plasmonic Fano resonances.
  • Spin Orbit interaction of light in micro and nano optical systems.

Singular optics

  • Genarating orbital angular momentum carrying beam using spatially tailored metasurfaces.
  • Orbital Hall effects of light.

Computational optics

  • FEM & FDTD simulation for studying optical responses.
  • Simulation of Mueller matrix for the desired smaples.

Polarization optics

  • Basic studies on polarization (spin)optical effects.
  • Theoretical and experimental studies on polarization (Mueller matrices, Stokes vectors, Jones matrices) and coherence characteristics of scattered light in random medium.

Biophotonics

  • Develop novel optical spectroscopic approaches to probe sub-diffractional information on the morphology of complex systems such as biological tissues.
  • Mueller matrix polarimetry and its applications in biophotonics.
  • Investigate various optical spectroscopic approaches (Elastic scattering, Fluorescence, Raman) for probing biological systems and other complex systems.
