Indistinguishability limit for off-axis vortex beams in uniaxial crystals.
The circular polarization components of a vortex beam in a uniaxial crystal exhibit complex propagation characteristics. We demonstrate how the amount of splitting may be distinguished by use of a vortex beam. We predict and experimentally verify a threshold angle subtending the crystal and beam axes, below which the splitting is indistinguishable.

متن کاملPropagation Properties of Partially Coherent Lorentz-Gauss Beams in Uniaxial Crystals Orthogonal to the X-Axis
Analytical expressions of the elements of a cross spectral density matrix are derived to describe the partially coherent Lorentz-Gauss beam propagating in uniaxial crystals orthogonal to the x-axis. The intensity and degree of polarization for the partially coherent Lorentz-Gauss beam propagating in uniaxial crystals orthogonal to the x-axis are also presented. The evolution properties of the p...

متن کاملUniaxial symmetry in nematic liquid crystals
Within the Landau-de Gennes theory of liquid crystals, we study theoretically the equilibrium configurations with uniaxial symmetry. We show that the uniaxial symmetry constraint is very restrictive and can in general not be satisfied, except in very symmetric situations. For oneand two-dimensional configurations, we characterize completely the uniaxial equilibria: they must have constant direc...
