Enhanced Spin-Orbit Interaction of Light through Complex Fresnel Reflection
Dileep Kumar Upadhyay, Nirmal K. Viswanathan
Spin-orbit interaction (SOI) of light manifests as the generation of a spin-dependent vortex beam and the spin-Hall effect when a spin-polarized beam interacts with an optical inte…

Extreme Cross-polarization Extinction Method for Quantification of Residual Crystal Anisotropy
Upasana Baishya, Nirmal K Viswanathan
The high-extinction cross-polarization measurement of a paraxial laser beam results in a Hermite-Gaussian ()-like four-lobes with a dark-centered cross pattern. The…
