Broadband arrayed waveguide gratings on InP

Optical and Quantum Electronics, 2007
Broadband arrayed waveguide gratings on InP are presented using a novel S-shape design. This design was utilized to accommodate the large free spectral range required for broadband operation. Four and eight channel AWGs with a wavelength channel spacing of 18 nm are discussed.

Modeling and design of arrayed waveguide gratings

Journal of Lightwave Technology, 2002
The purpose of this paper is twofold. First, a simple but comprehensive and powerful arrayed-waveguide grating (AWG) field model is presented which, based on Fourier optics, borrows some principles of that developed by Takeouchi and coworkers [see, Opt. Express, vol. 6, p.

Imaging errors in arrayed waveguide gratings

Optical and Quantum Electronics, 2003
A detailed assessment of imaging errors in arrayed waveguide gratings (AWG) is presented, focussing on possible design related imaging errors as well as on typical imaging errors mediated by the fabrication process. From a design point of view, special interest is drawn to the effect of coupling within the array of grating waveguides and to the impact ...

Birefringence compensated arrayed waveguide grating

SPIE Proceedings, 2014
In this paper we review our work on birefringence compensated arrayed waveguide grating. We elaborate on a birefringence compensation technique based on angled star couplers in arrayed waveguide grating (AWG) and discuss several demonstrations both in low-index-contrast and high-index-contrast material systems.

Adding functionalities to an arrayed waveguide grating

2012 IEEE 27th Convention of Electrical and Electronics Engineers in Israel, 2012
Different functionalities for an arrayed waveguide grating (AWG) configuration are described, showing that this widely used device can be designed not only to frequency multiplex/demultiplex optical channels, but also to implement the discrete Fourier transform (DFT) and the discrete fractional Fourier transform (DFrFT) of a signal, in all-optical ...

Temperature-insensitive arrayed waveguide gratings on InP substrates

Proceedings of Optical Fiber Communication Conference (, 1998
A temperature insensitive arrayed waveguide grating (TI-AWG) with an InGaAsP-InP material system is proposed. Less than 0.1 /spl Aring///spl deg/C temperature dependence for all eight channels was achieved for the first time even though we used the InGaAsP-InP material system.

Wavelength tuning using an arrayed waveguide gratings demultiplexer

Microwave and Optical Technology Letters, 2009
AbstractA novel wavelength tuning method using a specially designed arrayed waveguide gratings (AWG) demultiplexer was demonstrated. It was found that the transmission wavelengths of the AWG channels change linearly with the scanning of the input fiber along the facet of the input coupler of the AWG device.

An optical packet network based on Arrayed Waveguide Gratings

2003
Die vorliegende Arbeit beschreibt eine neuartige Architektur optischer Multihop-Packetnetze und untersucht daraus hervorgehende Zugriffsprotokolle und Fairnessalgorithmen. Die Netzarchitektur basiert auf einem (NxN) AWG, einem passiven Bauelement, das ähnlich einem Prisma in der Lage ist, Wellenlängen zu demultiplexen bzw.
