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.

Calculate the response of a 1x8 arrayed waveguide grating (AWG) working as a demultiplexer. An INTERCONNECT compact model is initially used for quick analysis. Component-level simulations using varFDTD are carried out for more realistic results. The final design can be exported to a GDS file for fabrication.

The operation principle of a conventional AWG is described as follows. A light beam exiting from a suitable waveguide aperture enters into a first free propagation region (FPR) and diverges. This diverging light beam is then coupled in an array of waveguides and propagates through these waveguides to a second FPR.

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.

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. The TiN heater is designed for uniform waveguide heating and wavelength detuning.

InP-based AWG is a semiconductor-based AWG that can be integrated to multiple active devices such as optical ampli˜ers and switches on a single chip. InP-based AWG can be manufactured in a compact package due to the large index-contrast of InP-based waveguides. The optical attenuation, coupling losses, and crosstalk performance

Particularly for AWGs with large numbers of channels, a high precision of the fabrication is required for achieving a low channel cross-talk. AWGs can be realized with different material systems, e.g. based on fused silica (SiO 2), indium phosphide (InP), or silicon (Si).

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.

2004年6月7日 · As AWG applications, I present new types of AWG modules such as a dynamic gain equalizer and a variable optical attenuator (VOA) MUX/DEMUX. Both of these will play an important role for next-generation wavelength-division multiplexing networks.

In this Letter, a 16 channel 200 GHz wavelength tunable arrayed waveguide grating (AWG) is designed and fabricated based on the silicon on insulator platform. Considering that the performance of the AWG, such as central wavelength and crosstalk, is sensitive to the dimension variation of waveguides, the error analysis of the AWG with width ...
