In this paper, we report the morphological transformations of vector-field singularities (V-
points) under symmetric and asymmetric perturbation using a diamond-shaped diffracting …

In optical testing, the well-known peak valley detection ambiguity exhibited by degenerate
interference intensity patterns is due to phase. The interplay between phase and …

Optical tweezers work on the principle that microscopic particles may be immobilized by the
application of an intense photon flux, which may be attained under tight focusing conditions …

Polarization singularities are point singularities in vector fields where azimuth of polarization
ellipse is not defined. C points and V points are generic polarization singularities. We report …
