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 .
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
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 ...
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 ...
Increasing current in the gain region causes a red shift in laser output due to heating. The reflectivity curve of the passive grating does not change. As a result, the grating will experience loss of reflectivity at the longer wavelengths, and eventually will induce a discontinuous blue shift in the wavelength to find a higher gain mode.
A fiber laser (or fibre laser in Commonwealth English) is a laser in which the active gain medium is an optical fiber doped with rare-earth elements such as erbium, ytterbium, neodymium, dysprosium, praseodymium, thulium and holmium. They are related to doped fiber amplifiers, which provide light amplification without lasing.
Treatments include dietary recommendations such as eating more fiber and probiotics or reducing the consumption of fatty foods and caffeine. Laxatives are also commonly recommended to improve IBS ...
The grating waveguides consists of many waveguides, each having a constant length increment (ΔL). Light is coupled into the device via an optical fiber (1) connected to the input port. Light diffracting out of the input waveguide at the coupler/slab interface propagates through the free-space region (2) and illuminates the grating with a ...
