Conical diffraction of linearly polarised light controls the angular position of a microscopic object
(2010)Conical diffraction of linearly polarised light in a biaxial crystal produces a beam with a crescent-shaped intensity profile. Rotation of the plane of polarisation produces the unique effect of spatially moving the ... -
The creation and annihilation of optical vortices using cascade conical diffraction
(2011)Internal conical diffraction produces a superposition of orthogonally polarised zero- and first-order Bessel like beams from an incident circularly polarised Gaussian beam. For right-circularly polarised light, the first-order ... -
Generation of continuously tuneable fractional optical orbital angular momentum using internal conical diffraction
(2010)Abstract: When a left-circularly polarised Gaussian light beam, which has spin angular momentum (SAM) Jsp = ?? = 1? per photon, is incident along one of the optic axes of a slab of biaxial crystal it undergoes internal ...
