Diffraction analysis of dielectric surface-relief gratings
Journal of the Optical Society of America, 1982Diffraction by a dielectric surface-relief grating is analyzed using rigorous coupled-wave theory. The analysis applies to arbitrary grating profiles, groove depths, angles of incidence, and wavelengths. Example results for a wide range of groove depths are presented for sinusoidal, square-wave, triangular, and sawtooth gratings.

Research on slanted trapezoidal surface relief grating
Holography, Diffractive Optics, and Applications IX, 2019With the rapid development of augmented reality technology, people can clearly see the superposition of virtual and real world images at the same time. The diffractive optical waveguide has obvious advantages over the geometric optical waveguide because of its high diffraction efficiency, light weight and difficulty in generating ghost images ...

A detailed study of metallic surface-relief grating
Optik, 2013Abstract This paper presents a more detailed interaction of an electromagnetics light with a metallic surface-relief subwavelength grating utilizing the rigorous coupled-wave analysis. The focus of this work is the accurate modeling of undetermined aspects of diffraction patterns produced by binary metallic grating structures, specially gold grating.

Formation and dynamics of polymer surface relief gratings
Applied Surface Science, 2001Abstract Time resolved VIS and X-ray scattering experiments have been performed during the formation of a surface relief grating on a polymer film containing an azobenzene side-chain homopolymer (poly{(4-nitrophenyl)[4-[[2-(methacryloyloxy)ethyl]ethylamino]phenyl]diazene} (pDR1M), TG=129°C) upon holographic exposure with circularly polarised laser ...

Diffraction by surface-relief gratings with conic cross-sectional grating shapes
Journal of the Optical Society of America A, 1989Diffraction of plane waves by dielectric surface-relief gratings with conic (elliptic, hyperbolic, parabolic) cross-sectional grating shapes is analyzed, using a simple transmittance theory. Integral expressions for the complex amplitudes of the diffracted waves are given for these structures.

Surface plasmon interference lithography with a surface relief metal grating
Optics Communications, 2013A surface plasmon interference lithography method with a surface relief metal grating is proposed. The interference of the surface plasmon waves produced by a surface relief metal grating with a large feature size at the interface between the surface relief metal grating and a photoresist layer is studied by the finite element method. Numerical results

Polarization gratings with surface relief in dyed gelatin and their postdevelopment diffraction
Applied Optics, 2002Some characteristics of dyed gelatin films when polarization gratings are recorded are reported. Two dyes, Malachite Green and Methylene Blue, are used in our experiment. In particular, no dichromate was added to Methylene Blue plates before or after exposure.

Nonlinear optics and surface relief gratings in alkynyl–ruthenium complexes
Journal of Optics A: Pure and Applied Optics, 2009Generally, the organometallic complexes rich in carbon and containing π-conjugated chains are materials interesting for the study of electronic transfer processes. Currently, the ruthenium–acetylide organometallic complexes form part of the most studied organometallic compounds in nonlinear optics.

Formation of Surface Relief Gratings: Effect of the Density of the Host Material
The Journal of Physical Chemistry B, 2012We use molecular dynamics simulations to investigate the effect of the density of the host material on the isomerization-induced diffusion mechanism that results in surface relief gratings formation. We find that a decrease in density increases the diffusion coefficient in a similar way for driven and spontaneous diffusion.

Polarization analysis of surface-relief D-fiber Bragg gratings
Applied Optics, 2007Surface-relief fiber Bragg gratings exhibit substantially more polarization dependence than standard fiber Bragg gratings. Using D-fiber with different core orientations, surface-relief gratings are analyzed and fabricated to determine the polarization dependence.
