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.

This page describes basics of AWG (Arrayed Waveguide Grating) used in Optical fiber. It mentions operation of Arrayed Waveguide Grating(AWG) as optical MUX and DEMUX. The features or characteristics of Optical Arrayed Waveguide Grating are mentioned.

Arrayed waveguide gratings are mainly applied in optical fiber communication systems, in particular in those based on multi-channel transmission with wavelength division multiplexing (WDM), where individual wavelength channels must be combined or separated.

Input Fiber Free Propagation Region (FPR) Output Fiber Operation Principle and Device Characteristics An AWG is made up of mainly 3 parts, which are the input/output ˜ber, the Free Propagation Region (FPR), and array waveguides. Light wave of multiple di˚erent wavelengths enter the FPR through the input ˜ber.

2020年6月11日 · Here, we demonstrate an 8-channel thermo-optic tunable AWG at 2 μm via silicon photonic multi-project wafer shuttle run. The device is fully compatible with standard foundry fabrication process without customization.

An ultra-thin core waveguide AWG 1,2, as illustrated in Fig. 1, uses a wide single-mode waveguide which reduces scattering losses due to sidewall imperfections, and increases the coupling from a typical fiber mode due to the large mode size.

2021年6月10日 · For the development of minimized and high-rate photonic-integrated fiber Bragg grating interrogation (FBGI) systems, arrayed waveguide grating (AWG) has been widely used as one of the critical components. In this paper, we present an 8-channel SOI-based AWG for a photonic integrated FBG interrogation microsystem.

Array waveguide grating is usually used in WDM system optical (DE) multiplexers of Wavelength division multiplexing WDM system. These devices can compound the lights with many wavelengths into a single optical fiber, so as to improve the transmission efficiency of …

Arrayed-waveguide gratings (AWG) are based on the principles of diffractions. An AWG device is sometimes called an optical waveguide, a waveguide grating router, a phase array, or a phasar. An AWG device consists of an array of curved-channel waveguides with a fixed difference in the length of optical path between the adjacent channels.
