Polarization singularities and orbital angular momentum sidebands from rotational symmetry broken by the Pockels effect

Abstract

The law of angular momentum conservation is naturally linked to the rotational symmetry of the involved system. Here we demonstrate theoretically how to break the rotational symmetry of a uniaxial crystal via the electro-optic Pockels effect. By numerical method based on asymptotic expansion, we discover the 3D structure of polarization singularities in… (More)
