Singular polarization eigenstates in anisotropic stratified structures
Applied Optics, 2000A new optical element that displays singular polarization eigenstates is proposed. It consists of a planar stratified structure composed of alternate gyrotropic and birefringent layers. The orthogonality of the polarization eigenstates is lost because of anisotropic reflections at the interfaces, which are enhanced by the special condition chosen for ...

Singular Polarizations and Ellipsoid Packings
International Mathematics Research Notices, 2012We prove in this paper that any 4-dimensional symplectic manifold is essentially made of finitely many symplectic ellipsoids. The key tool is a singular analogue of Donaldson’s symplectic hypersurfaces in irrational symplectic manifolds.

Synthesizing polarization singularity lattices using phase ramps
Journal of the Optical Society of America AIn this paper, a novel methodology for generating polarization singularity lattices using ramp phase structures in a polarization interferometer is presented. By applying differential tilts to distinct regions within the wavefront using a spatial light modulator, a phase-discontinuity line separating the two regions is formed.
