Diffraction grating - Wikipedia

In optics, a diffraction grating is an optical component with a periodic structure that splits and diffracts light into several beams travelling in different directions. The emerging coloration is a form of structural coloration. The directions of these beams depend on the spacing of the grating and the wavelength of the light so that the grating acts as the dispersive element.

OSA | Full vector complex coupled mode theory for tilted

A full vector complex coupled mode theory (CMT) for the analysis of tilted fiber gratings is presented. With the combination of the perfectly matched layer (PML) and the perfectly reflecting boundary (PRB), the continuous radiation modes are well represented by a set of discrete complex modes. Simulation of coupling to radiation modes is greatly simplified and may be treated in the same

Echelle grating - Wikipedia

Echelle grating - Wikipedia

An echelle grating (from French échelle, meaning "ladder") is a type of diffraction grating characterised by a relatively low groove density, but a groove shape which is optimized for use at high incidence angles and therefore in high diffraction diffraction orders allow for increased dispersion (spacing) of spectral features at the detector, enabling increased differentiation

Bearing bars and cross bars are precision slotted, assembled in egg-crate fashion and hydraulically pressed together to form a tightly locked, rigidly stable panel grid. This grating is available in spacings, which provide a 1/4" or 1/2" opening in conformance with provisions for the “Americans with Disabilities Act” (July 1991).

A Pictorial Introduction to Fourier Analysis/Synthesis

Basics of Gratings (sinewave and square-wave) A grating is a repeating sequence of light and dark bars. One adjacent pair of a light and a dark bar makes up one cycle. These cycles repeat over and over in a grating. Typically, we think of these gratings as having sharp edges like the bars shown in Figure 1 below. Figure 1. A grating composed of
