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…
Generic Optical Singularities and Beam-field Phenomena due to General Paraxial Beam Reflection at a Plane Dielectric Interface
Anirban Debnath, Nirmal K. Viswanathan
A single paraxial beam reflection at a plane dielectric interface, configured appropriately, can lead to the formation of a polarization singularity in the inhomogeneously polarize…
Orbital Angular Momenta and Geometric Phase Characteristics of Spin-polarized Components of a General Paraxial Beam-field
Anirban Debnath, Nirmal K. Viswanathan
We explore a subtle and fundamental nature of spin-orbit interaction (SOI) in a general paraxial beam-field by mathematically characterizing the orbital angular momentum (OAM) flux…
