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…
Mueller matrix spectroscopy of Fano resonance in Plasmonic Oligomers
Shubham Chandel, Ankit K Singh, Aman Agrawal +4
Fano resonance in plasmonic oligomers originating from the interference of a spectrally broad superradiant mode and a discrete subradiant mode is under intensive recent investigati…
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…
