Spin-to-orbital momentum conversion via electro-optic Pockels effect in crystals

Spin-to-orbital angular momentum conversion in dielectric metasurfaces: erratum.

We would like to clarify our paper [Opt. Express25, 377 (2017)] abstract sentence "These beams carry orbital angular momentum proportional to the number of intertwined helices constituting the wavefront."

Femtosecond electro-optic effect in (Cd,Mn)Te single crystals

We present our studies on the femtosecond electro-optic (EO) effect in high quality Cd0.88Mn0.12Te (CMT) single crystals, grown using a modified vertical Bridgman method. Our time-resolved experiments were performed using a coplanar transmission line setup, which incorporated a free-standing, low-temperature-grown GaAs photoconductive switch as a subpicosecond electrical pulse generator and the...

Electro-Optic Kerr Effect in Polymer-Stabilized Isotropic Liquid Crystals

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

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 terms of C lines and L surfaces embedded ...

Spin-to-orbital angular momentum conversion in focusing, scattering, and imaging systems.

We present a general theory of spin-to-orbital angular momentum (AM) conversion of light in focusing, scattering, and imaging optical systems. Our theory employs universal geometric transformations of non-paraxial optical fields in such systems and allows for direct calculation and comparison of the AM conversion efficiency in different physical settings. Observations of the AM conversions usin...
