Monochromatic light of wavelength 694. nm is incident on a diffraction grating with 2192 lines per centimetre. What is the highest order maximum that can be observed? 2.
Corn syrup films are used to replicate holograms in order to fabricate micro-structural patterns without the toxins commonly found in photosensitive salts and dyes. We use amplitude and relief masks with lithographic techniques and rubbing techniques in order to transfer holographic information to corn syrup material. Holographic diffraction patterns from holographic gratings and computer

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
HOLO / OR offers Diffraction gratings that are Binary Phase Gratings. These are a special case of a 1D Damman grating with a duty cycle of 50% within a period. Our gratings are transmission gratings, but can be offered in reflective versions as desired .
In this work, we present a resonant, dielectric waveguide device based on distributed Bragg gratings for label-free biosensing applications. The refractive index sensitive optical transducer aims at improving the performance of planar waveguide grating sensor systems with limited Q-factor and dynamic range by combing the advantages of resonant cavities, such as a multitude of resonance peaks

More particularly, this invention relates to a high-contrast tilting-ribbon blazed grating. BACKGROUND OF THE INVENTION Bloom et al. in . Pat. No. 5,311,360, entitled “Method and Apparatus For Modulating A Light Beam,” teach a grating light valve™ type device which operates in a reflection mode and a diffraction mode.
Diffraction gratings were discovered during the 18th century, and they are now widely used in spectrometry analysis, with outstanding achievements spanning from the probing of single molecules in biological samples to the analysis of solar systems in astronomy. The fabrication of high-quality diffraction gratings requires precise control of the period at a nanometer scale.

DIFFRACTION GRATINGS 35 slit images are formed only where the grating surface itself is out of focus, so surface blemishes are observed only in terms of their effect on the source light. Whether to discard a given grating because of its limitations, or to retain it for its virtues, is a decision that must be made regarding every good grating.
Grating elements can have luminances other than that of sharp-edged bars. If the graph of a grating is sinusoidal (see top panel in the illustration), the grating looks like a set of blurry light and dark bars and it is called a sine-wave grating. Sine-wave gratings are used extensively in optics to determine the transfer functions of lenses. A
Metasurfaces are artificially structured thin films with unusual properties on demand. Different from metamaterials, the metasurfaces change the electromagnetic waves mainly by exploiting the boundary conditions, rather than the constitutive parameters in three dimensional (3D) spaces. Despite the intrinsic similarities in the operational principles, there is not a universal theory available

A new class of planar optics has emerged using subwavelength gratings with a large refractive index contrast, herein referred to as high-contrast gratings (HCGs). This seemingly simple structure lends itself to extraordinary properties, which can be designed top-down based on intuitive guidelines. The HCG is a single layer of high-index material that can be as thin as 15% of one wavelength.
