Reflectivity of the quantum grating and the grating polariton
Physical Review B, 1995We solve the problem of the scattering of an electromagnetic plane wave from a planar array of equispaced cylindrical scatterers with strong resonances. We apply this theory to calculate the reflectivity of an array of quantum wires using the electromagnetic properties of the single wire as the only input.

Novel immersion grating, VPH grating and quasi-Bragg grating
SPIE Proceedings, 2006We have successfully fabricated germanium immersion gratings with resolving power of 45,000 at 10 μm by using a nano precision 3D grinding machine and ELID (ELectrolytic In-process Dressing) method. However the method spends large amount of machine times.

Mechanisms of Grating Formation and Grating Materials [PDF]
, 1986 In the following section, different mechanisms of light-induced changes of optical material properties are described. Often these changes are considered to be due to some specific material excitation (e.g., electron density, temperature). This is, however, a simplified description.

Grating interferometers for producing large holographic gratings
Applied Optics, 1990Methods for producing large holographic diffraction gratings are described. In particular, the advantages of using a grating interferometer illuminated with a noncollimated beam from either an extended monochromatic source or an extended polychromatic source are described along with some of the problems that arise and methods to solve them ...

Applied Optics, 1995
A grating-pair device is useful for producing negative group velocity dispersion of temporal optical signals. When high dispersion is needed or large bandwidth is involved, higher-order dispersion terms become significant. The grating triplet is a new approach to create dispersion that can produce negative or positive group-velocity dispersion without ...

AIP Conference Proceedings, 1982
I show that laser grating accelerators may encounter serious difficulties in operating near or even below the damage threshold caused by the formation of a dense plasma above the grating, which obscures the grating shape.

Birefringence Bragg Binary (3B) grating, quasi-Bragg grating and immersion gratings
SPIE Proceedings, 2014A volume phase holographic (VPH) grating achieves high angular dispersion and very high diffraction efficiency for the first diffraction order and for S or P polarization. However the VPH grating could not achieve high diffraction efficiency for non-polarized light at a large diffraction angle because properties of diffraction efficiencies for S and ...

On the production of diffraction grating. I. The copying of plane gratings
Vacuum, 1951The paper is the first of a series describing the development at the National Physical Laboratory of new methods of making, copying and testing diffraction gratings. It describes the development of a method devised by Merton (1950) for copying a plane grating by using a plastic pellicle to transfer the cast of the grating to a gelatine surface.
