Retrieving intrinsic polarization anisotropies of nanostructures using differential Mueller matrix polarimetry
Jeeban Kumar Nayak, Ebru Buhara, Olivier J. F. Martin
Accurate characterization of polarization dependent light matter interactions in nanostructured systems is paramount for the development of chiral metasurfaces. It is also often ch…
Spin-Split Dispersion of Leaky Surface plasmons in Inversion- Symmetric System
Sujit Rajak, Nishkarsh Kumar, Dheeraj Yadav +6
Spin-dependent dispersion and Rashba effect are manifestations of universal spin orbit interaction associated with the breaking of the spatial inversion symmetry in condensed matte…
Scalable Generalized Meta-Spanners Enabling Parallel Multitasking Optical Manipulation
Tianyue Li, Wenyu Gao, Boyan Fu +12
Optical manipulation techniques offer exceptional contactless control but are fundamentally limited in their ability to perform parallel multitasking. To achieve high-density, vers…
Micromotors Driven by Spin-Orbit Interaction of Light: Mimicking Planetary Motion at the Microscale
Ram Nandan Kumar, Jeeban Kumar Nayak, Subhasish Dutta Gupta +2
We introduce a new class of optical micromotors driven by the spin-orbit interaction of light and spin-driven fluid flows leading to simultaneous rotation and revolution of the mic…
Signum phase mask differential microscopy
Jeeban Kumar Nayak, Niladri Modak, Sayan Ghosh +1
We propose and experimentally demonstrate a differential microscopy method to obtain simultaneous amplitude, phase, and quantitative polarization gradient imaging in a single exper…
Inhomogeneous Polarization Transformation Reveals PT-Transition in non-Hermitian Optical Beam Shift
Niladri Modak, Swain Ashutosh, Shyamal Guchhait +5
Despite its non-Hermitian nature, the transverse optical beam shift exhibits both real eigenvalues and non-orthogonal eigenstates. To explore this unexpected similarity to typical…
Probing inhomogeneous and dual asymmetric angular momentum exploiting spin-orbit interaction in tightly focused vector beams in optical tweezers
Ram Nandan Kumar, Jeeban Kumar Nayak, Anand Dev Ranjan +3
The spin-orbit interaction (SOI) of light generated by tight focusing in optical tweezers has been regularly employed in generating angular momentum - both spin and orbital - in tr…
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…
Unravelling the role of waveguide-plasmon strong coupling, avoided crossing and natural weak value amplification on the enhanced Faraday effect in hybrid magneto-plasmonic systems
Jeeban K Nayak, Shyamal Guchhait, Ankit K Singh +1
Enhancement of magneto-optical effects in hybrid magneto-plasmonic systems has attracted considerable recent attention owing to their potential for building non-reciprocal nanophot…
Weak value amplification using spectral interference of Fano resonance
Shyamal Guchhait, Athira B S, Niladri Modak +4
The extraordinary concept of weak value amplification and a number of other seemingly counter-intuitive wave phenomena are manifestations of fine interference effects. Taking examp…
