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 ...

A simple acoustic scanning device has been devised in which a chirped SAW beam is converted into a focused scanning bulk wave beam by coherent scattering from a grating of parallel grooves. The device can operate in both transmitting and receiving modes, and is applicable to the acoustic imaging of objects in real time.

Chiral gratings with double helix symmetry were produced by twisting glass optical fiber with a noncircular core cross section as it passed through a miniature oven. We observed polarization-selective transmission in chiral fibers with pitches of tens of micrometers. Two modes of optical interaction were differentiated.

A circular Dammann grating that can produce circular equal intensities at various orders in the far field is described. A set of parameters such as order, circular number, uniformity, and diffraction efficiency has been defined to describe the novel diffractive phase elements.

We propose a method of optical waveguiding, which relies on Bragg diffractions from a 1D grating that gives rise to waveguiding in the direction normal to the grating wave vector. The waveguide structure consists of a shallow 1D grating that has a bell- or trough-shaped amplitude in the confinement direction.

A simple closed-form description of grating-assisted coupling between twin cores is presented. It is exact in the limit of weakly coupled cores and weak grating perturbations.
