    en.wikipedia.org/wiki/Fiber_Bragg_grating

    A fiber Bragg grating (FBG) is a type of distributed Bragg reflector constructed in a short segment of optical fiber that reflects particular wavelengths of light and transmits all others. This is achieved by creating a periodic variation in the refractive index of the fiber core, which generates a wavelength-specific dielectric mirror .

    en.wikipedia.org/wiki/Addressed_fiber_Bragg...

    The concept of addressed fiber Bragg structures was introduced in 2018 by Airat Sakhabutdinov [1] and developed in collaboration with his scientific adviser, Oleg Morozov. . The idea emerged from the earlier works of Morozov and his colleagues, [2] [3] where the double-frequency optical radiation from an electro-optic modulator was used for the definition of the FBG central wavelength based on ...

    en.wikipedia.org/wiki/Distributed_Bragg_reflector

    Time-resolved simulation of a pulse reflecting from a Bragg mirror. A distributed Bragg reflector (DBR) is a reflector used in waveguides, such as optical fibers.It is a structure formed from multiple layers of alternating materials with different refractive index, or by periodic variation of some characteristic (such as height) of a dielectric waveguide, resulting in periodic variation in the ...

    en.wikipedia.org/wiki/Optical_add-drop_multiplexer

    Optical add-drop multiplexer, using a fiber Bragg grating and two circulators. An optical add-drop multiplexer (OADM) is a device used in wavelength-division multiplexing (WDM) systems for multiplexing and routing different channels of light into or out of a single-mode fiber (SMF).

    Chiral-fiber gratings are a variation on conventional fiber Bragg gratings. Rather that write gratings on glass, chiral gratings are mechanical gratings microformed into glass. Chiral Photonics , a New Jersey company, is the leading developer of this technology.

    The refractive index profile of the fiber core shows the change of the refractive index along the core. The spectral response on the Fiber Bragg Grating shows how the incident broadband signal is split into the transmitted and reflected components, about the Bragg wavelength.
