Abstract: Method for fabrication of vector vortex waveplates of improved quality due to reduced singularity size and widened spectral band, the method comprising creating a boundary condition for vortex orientation pattern of a liquid crystal polymer on a substrate using materials with reversible photoalignment, equalizing exposure energy over the area of the waveplate by redistributing the energy of radiation used for photoalignment from the center of the beam to its peripheries, and using vector vortex waveplate as a linear-to-axial polarization converter. Fabrication of spectrally broadband vector vortex waveplates further comprises two or more liquid crystal polymer layers with opposite sign of twist.

Abstract: A method of fabricating a liquid crystal polymer film includes providing a support substrate having a surface having a shape arranged to define a form of a liquid crystal polymer film to be fabricated; applying a layer of a photoaligning material over the surface of the support substrate, the photoaligning material having an absorption band; exposing the layer of photoaligning material to a light having a linear polarization and the light comprising a wavelength within the absorption band to convert the layer of photoaligning material into a layer of photoaligned material; applying a layer of a polymerizable liquid crystal over the layer of photoaligned material; performing photopolymerization of the layer of polymerizable liquid crystal to form a liquid crystal polymer film; applying a solvent to the layer of photoaligned material, the solvent formulated to dissolve the photoaligned material to thereby release the liquid crystal polymer film from the support substrate; and removing the liquid crystal polymer film from the support substrate.

Abstract: Lenses, devices, apparatus, systems, methods of manufacturing and fabricating an ophthalmic lens device for correction of human vision. The ophthalmic lens device includes at least one diffractive waveplate coating with an optical axis orientation pattern designed to correct the vision of individual patients. The ophthalmic lens device including diffractive waveplate coating may also provide a portion of the required vision correction by means of refraction of light by curved surfaces of a dielectric material.

Abstract: Diffractive optical structures, lens, waveplates, systems and methods of combinations of CDWs (cycloidal diffractive waveplates) and PVGs (polarization volume gratings) that result in high efficiency polarization-insensitive diffraction. Although our modelling and experiments were performed for structures with optical axis orientation periodic along one of the Cartesian coordinates parallel to the plane of the structure, the results are applicable to more complex structures such as diffractive waveplate lenses. The focusing performance of such structures can be predicted by considering the structure to be locally periodic along one axis.
