Arrayed waveguide gratings (AWG) are commonly used as optical (de)multiplexers in wavelength division multiplexed (WDM) systems. These devices are capable of multiplexing many wavelengths into a single optical fiber , thereby increasing the transmission capacity of optical networks considerably.
AWG is an abbreviation for American wire gauge. AWG may also refer to: In science and technology: Arbitrary waveform generator, a piece of electronic test equipment used to generate electrical waveforms; Arrayed waveguide grating, in telecommunications, an optical (de)multiplexing device
English: An Arrayed-Waveguide Grating is an optical de-/multiplexer used in telecommunication. The incoming light (1) traverses a free space (2) and enters a bundle of optical fibers or channel waveguides (3) .
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 ...
Grating-coupled interferometry (GCI) is a biophysical characterization method mainly used in biochemistry and drug discovery for label-free analysis of molecular interactions. Similar to other optical methods such as surface plasmon resonance (SPR) or bio-layer interferometry (BLI), it is based on measuring refractive index changes within an ...
A typical radiation pattern of phased arrays whose inter-element spacing is greater than half a wavelength, hence the radiation pattern has grating lobes.. For discrete aperture antennas (such as phased arrays) in which the element spacing is greater than a half wavelength, a spatial aliasing effect allows plane waves incident to the array from visible angles other than the desired direction ...
