4 Arrayed Waveguide Gratings

An optical packet network based on arrayed waveguide gratings

This work presents PrimeNet, a novel architecture for optical multihop networks and investigates a Medium Access Control (MAC) protocol and a fairness algorithm for it. The network architecture is based on an Arrayed Waveguide Grating, a passive optical device that is used widely as wavelength multiplexer/demultiplexer, today. Relying on a physical star architecture logical rings are set up on ...

Silicon arrayed waveguide gratings at 2.0-μm wavelength characterized with an on-chip resonator.

Low-loss arrayed waveguide gratings (AWGs) are demonstrated at a 2.0-μm wavelength. These devices promote rapidly developing photonic applications, supported by the recent development of mid-infrared lasers integrated on silicon (Si). Multi-spectral photonic integrated circuits at 2.0-μm are envisioned since the AWGs are fabricated with the 500-nm-thick Si-on-insulator platform compatible with ...

Miniature Spectrographs: Characterization of Arrayed Waveguide Gratings for Astronomy

We present results from a laboratory characterization of integrated photonic arrayed-waveguide grating chips, which are a modified version of commercial arrayed-waveguide grating multiplexors, for the purposes of creating an integrated photonic spectrograph. Using a robust probing setup we measure the peak total efficiency of the chips to be ~75%. We measure the spectral resolution full-width h...

Compact chip-scale filter based on curved waveguide Bragg gratings.

We propose a method for miniaturization of filters based on curved waveguide Bragg gratings, so that long structures can be packed into a small area on a chip. This eliminates the stitching errors introduced in the fabrication process, which compromise the performance of long Bragg gratings. Our approach relies on cascading curved waveguide Bragg gratings with the same radius of curvature. An a...
