The end of one handle contains a food hopper with a grating cylinder and a crank for rotating the cylinder. The other section has a rounded surface that acts as a clamp, pressing the food to be grated into the grating cylinder. The hinged handles are held in one hand and squeezed so that the food presses against the grating cylinder.
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 ...
Graters produce shreds that are thinner at the ends than the middle. This allows the grated material to melt or cook in a different manner than the shreds of mostly uniform thickness produced by the grating blade of a food processor. Hand-grated potatoes, for example, melt together more easily in a potato pancake than food-processed potato shreds.
Microplane is a registered trademark [citation needed] of Grace Manufacturing Inc., a company that makes photo etched steel tools (surform tools) for grating, grinding and sanding. It was created by brothers Richard & Jeff Grace in the mid-1990s.
A distributed Bragg reflector laser (DBR) is a type of single frequency laser diode. Other practical types of single frequency laser diodes include DFB lasers and external cavity diode lasers. A fourth type, the cleaved-coupled-cavity laser has not proven to be commercially viable. VCSELs are also single frequency devices. [1]
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 ...
