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…
Tunable giant two-dimensional optical beam shift from a tilted linear polarizer
Niladri Modak, Sayantan Das, Priyanuj Bordoloi +1
We demonstrate an intriguing giant optical beam shift in a tilted polarizer system analogous to the Imbert-Fedorov shift in partial reflection around the Brewster's angle of incide…
Probing the rotational spin-Hall effect in higher order Gaussian beams
Ram Nandan Kumar, Yatish, Subhasish Dutta Gupta +2
Spin-to-orbit conversion of light is a dynamical optical phenomenon in non-paraxial fields leading to various manifestations of the spin and orbital Hall effect. However, effects o…
Direct observation of the effects of spin dependent momentum of light in optical tweezers
Debapriya Pal, Subhasish Dutta Gupta, Nirmalya Ghosh +1
We demonstrate that tight focusing of a circularly polarized Gaussian beam in optical tweezers leads to spin-momentum locking - with the transverse spin angular momentum density be…
Spectral singularity enhances transverse spin
Mounica Mahankali, Sudipta Saha, Nirmalya Ghosh +1
We study the transverse spin and the Belinfante spin momentum in a gain-loss balanced waveguide, known to be one of the first and most studied examples of -symmetric…
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…
