  3. Guided-mode resonance - Wikipedia

    en.wikipedia.org/wiki/Guided-mode_resonance

    An example of guided-mode resonance is a grating coupler, which is a region on top of or below a waveguide where there is a grating. Off-resonance light incident on the grating behaves almost the same as it would if it was incident in an area where there is no grating. Waveguides are usually made of dielectric and are transparent. For specific ...

  4. Blazed grating - Wikipedia

    en.wikipedia.org/wiki/Blazed_grating

    A special form of a blazed grating is the echelle grating. It is characterized by particularly large blaze angle (>45°). Therefore, the light hits the short legs of the triangular grating lines instead of the long legs. Echelle gratings are mostly manufactured with larger line spacing but are optimized for higher diffraction orders.

  5. Diffraction grating - Wikipedia

    en.wikipedia.org/wiki/Diffraction_grating

    A blazed diffraction grating reflecting only the green portion of the spectrum from a room's fluorescent lighting. For a diffraction grating, the relationship between the grating spacing (i.e., the distance between adjacent grating grooves or slits), the angle of the wave (light) incidence to the grating, and the diffracted wave from the grating is known as the grating equation.

  6. Fiber Bragg grating - Wikipedia

    en.wikipedia.org/wiki/Fiber_Bragg_grating

    Typically the grating period is the same size as the Bragg wavelength, as shown above. For a grating that reflects at 1,500 nm, the grating period is 500 nm, using a refractive index of 1.5. Longer periods can be used to achieve much broader responses than are possible with a standard FBG. These gratings are called long-period fiber grating ...

  7. Frequency-resolved optical gating - Wikipedia

    en.wikipedia.org/wiki/Frequency-resolved_optical...

    The two pulse copies are crossed at an angle and focused to a line instead of a point. This creates a varying delay between the two pulses along the line focus. In this configuration, it is common to use a home-made spectrometer, consisting of a diffraction grating and a camera, to capture the measurement.

    en.wikipedia.org/wiki/Estimation_of_signal...

    Estimation of signal parameters via rotational invariant techniques (ESPRIT), is a technique to determine the parameters of a mixture of sinusoids in background noise. This technique was first proposed for frequency estimation. [ 1 ]
