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…

Spin-orbit Interaction-mediated Measurement of Surface Chirality
Upasana Baishya, Nirmal K. Viswanathan
The spin-orbit interaction in a focused-reflected beam of light results in spatially non-uniform polarization in the beam cross-section due to the superposition of orthogonal field…

Optical Singularity Dynamics and Spin-Orbit Interaction due to a Normal-Incident Optical Beam Reflected at a Plane Dielectric Interface
Anirban Debnath, Nitish Kumar, Upasana Baishya +1
The degenerate case of normal incidence and reflection of an optical beam (both paraxial and non-paraxial) at a plane isotropic dielectric interface, which is azimuthally symmetric…
