    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 .

    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 ...

    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 ...

  7. Distributed-feedback laser - Wikipedia

    en.wikipedia.org/wiki/Distributed-feedback_laser

    A distributed-feedback laser (DFB) is a type of laser diode, quantum-cascade laser or optical-fiber laser where the active region of the device contains a periodically structured element or diffraction grating. The structure builds a one-dimensional interference grating (Bragg scattering), and the grating provides optical feedback for the
