Demonstration of Heterodyned Arrayed Waveguide Grating
Photonic Arrayed Waveguide Grating (AWG) spectrographs, currently in development at JPL/Caltech, are now achieving R~10,000, and with refined designs should achieve throughputs comparable to
(PDF) An Ultra-Compact, Narrow-Bandwidth, and High-Density
This device is based on an updated generation of arrayed waveguide gratings (AWG) named serial-AWG (SAWG). The design consists of 33 tunable optical delay lines and 10 output
Arrayed Waveguide Gratings – AWG
Figure 1: Structure of an arrayed waveguide grating. Particularly for AWGs with large numbers of channels, a high precision of the fabrication is required for achieving a low channel cross-talk.
Compact Silicon-Arrayed Waveguide Gratings with Low Nonuniformity
Array waveguide gratings (AWGs) have been widely used in multi-purpose and multi-functional integrated photonic devices for Microwave photonics (MWP) systems. In this paper, we
Custom Arrayed Waveguide Gratings with Improved Performance
In this review, an overview of the available methods for improving the bandwidth, spectral resolution, and transmission function shape of AWGs is provided. The working principle as well as the advantages
Design, fabrication and characterization of arrayed waveguide grating
Based on the same shapes of the arrayed waveguide and the numbers of output channels, the performance of AWG devices with the SU-8 core layer were better than those with the PMMA
High-Performance Compact 48-Channel Arrayed Waveguide Grating
Here, we simulate and design a compact 48-channel 100 GHz arrayed waveguide grating (AWG) based on a 2.0% high refractive index silica platform using the three-dimensional beam
Compact Arrayed Waveguide Gratings Fabricated on 800-nm-Thick Si
Abstract: Silicon nitride (Si 3 N 4) waveguide with thickness of >600 nm having strong mode confinement and anomalous group velocity dispersion (GVD) has today become the leading
