Journal ArticleDOI
Effects of plasticizer on the transient diffraction properties of polarization holographic gratings made from polarization-sensitive polymeric films
TL;DR: In this paper, anisotropic gratings were recorded by polarization holographic recording in azobenzene-containing polymeric films doped with a 9-ethylcarbazole (ECZ) plasticizer.
Journal ArticleDOI
Universal polarization terahertz phase controllers using randomly aligned liquid crystal cells with graphene electrodes.
TL;DR: A universal polarization terahertz (THz) phase controller is presented using a randomly aligned liquid crystal (LC) cell with graphene electrodes and it is demonstrated that the THz phase shift could be controlled by the applied voltage.
Journal ArticleDOI
Tunable dichroic polarization beam splitter created by one-step holographic photoalignment using four-beam polarization interferometry
TL;DR: In this article, a tunable dichroic polarization beam splitter (tunable DPBS) simultaneously performs the following functions: separation of a polarized incident beam into multiple pairs of orthogonally polarized beams, separation of the propagation direction of two wavelength incident beams, and control of both advanced polarization and wavelength separation capabilities.
Journal ArticleDOI

TL;DR: In this paper, a terahertz (THz) polarization converter using a twisted nematic (TN) liquid crystal (LC) cell was fabricated using poly(3,4-ethylenedioxythiophene)/poly(styrenesulfonate) (PEDOT/PSS) films.
Journal ArticleDOI
Three-dimensionally modulated anisotropic structure for diffractive optical elements created by one-step three-beam polarization holographic photoalignment
TL;DR: In this paper, a diffractive optical element with a three-dimensional liquid crystal alignment structure for advanced control of polarized beams was fabricated by a highly efficient one-step photoalignment method, where different two-dimensional continuous and complex alignment patterns were produced on two alignment films by simultaneously irradiating an empty glass cell composed of two unaligned photocrosslinkable polymer LC films with three-beam polarized interference beam.
