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…
Experimental Measurement of Transverse Spin Dynamics in the Nonparaxial Focal Region
Nitish Kumar, Cyriac Raju, Dinesh N. Naik +1
The superposition of complex optical fields in three-dimension (3D) is the basis of several non-trivial wave phenomena. Significant among them are the non-uniform polarization dist…
Complex far fields and optical singularities due to propagation beyond tight focusing: combined effects of wavefront curvature and aperture diffraction
Nitish Kumar, Anirban Debnath, Nirmal K. Viswanathan
All optical systems, which involve the collimation of a reflected, transmitted or scattered wave subsequent to tight focusing, are subject to two kinds of deviations. One is the wa…
