Observation of Non-Vanishing Optical Helicity in Thermal Radiation from Symmetry-Broken Metasurfaces
Xueji Wang, Tyler Sentz, Sathwik Bharadwaj +5
Spinning thermal radiation is a unique phenomenon observed in condensed astronomical objects including the Wolf-Rayet star EZ-CMa and the red degenerate star G99-47, due to existen…
Momentum domain polarization probing of forward and inverse spin Hall effect of leaky modes in plasmonic crystals
Jeeban Kumar Nayak, Harley Suchiang, Subir Kumar Ray +3
Simultaneous manifestation of both forward and inverse photonic Spin Hall effect in geometrically tailored anisotropic waveguided plasmonic crystal system is observed through the e…
Controlling Fano resonance using the Geometrical Phase of light in spatially tailored waveguided plasmonic crystals
Subir K. Ray, Ankit K. Singh, Ajmal +3
Fano resonance exhibiting an asymmetric spectral line shape is a universal phenomenon observed in diverse physical systems. Here we experimentally establish a direct link between t…
Weak value amplification using asymmetric spectral response of Fano resonance as a natural pointer
Ankit K. Singh, Subir K. Ray, Shubham Chandel +4
Weak measurement enables faithful amplification and high precision measurement of small physical parameters and is under intensive investigation as an effective tool in metrology a…
Polarization-tailored Fano interference in plasmonic crystals: A Mueller matrix model of anisotropic Fano resonance
S. K. Ray, S. Chandel, A. K. Singh +4
We present a simple yet elegant Mueller matrix approach for controlling the Fano interference effect and engineering the resulting asymmetric spectral line shape in anisotropic opt…
Transverse spin and transverse momentum in scattering of plane waves
Sudipta Saha, Ankit K. Singh, Subir K. Ray +3
We study the near field to the far field evolution of spin angular momentum (SAM) density and the Poynting vector of the scattered waves from spherical scatterers. The results show…
Complete polarization characterization of single plasmonic nanoparticle enabled by a novel Dark-field Mueller matrix spectroscopy system
Shubham Chandel, Jalpa Soni, Subir K. Ray +4
Information on the polarization properties of scattered light from plasmonic systems are of paramount importance due to fundamental interest and potential applications. However, su…
