Patent number: 10802302Abstract: The invention provides for lenses fabricated as planar thin film coatings with continuous structure. The lensing action is due to optical axis orientation modulation in the plane of the lens. The lenses of the current invention are fabricated using photoalignment of a liquid crystal polymer wherein the polarization pattern of radiation used for photoalignment is obtained by propagating the light through an optical system comprising a shape-variant nonlinear spatial light polarization modulators.Type: GrantFiled: October 24, 2018Date of Patent: October 13, 2020Assignees: Beam Engineering for Advanced Measurements Co., The United States of America as Represented by the Secretary of the ArmyInventors: Nelson Tabirian, Svetlana Serak, Diane Steeves, Brian Kimball

Patent number: 10107945Abstract: 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.Type: GrantFiled: February 28, 2014Date of Patent: October 23, 2018Assignee: Beam Engineering for Advanced Measurements Co.Inventors: Nelson Tabirian, Sarik Nersisyan
