Compact Waveguide Grating Array Demultiplexer
Integrated Photonics Research, 1996We demonstrate a novel generic design for waveguide grating array demultiplexers that reduces the chip size by 50%. We experimentally verified that there is no degradation in performance relative to conventional designs.

Broadband arrayed waveguide gratings on InP
Optical and Quantum Electronics, 2007Broadband 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, 2002The 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, 2003A 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, 2014In 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.

Arrayed-waveguide grating multiplexer with flat spectral response
Optics Letters, 1995The design principle of a single-mode arrayed-waveguide grating multiplexer with flat spectral response is proposed on the basis of a discrete Fourier transform. By a beam propagation-method simulation, a flat spectral region (within 1-dB loss increase) is obtained over 57.2 GHz for 100-GHz channel spacing.

Adding functionalities to an arrayed waveguide grating
2012 IEEE 27th Convention of Electrical and Electronics Engineers in Israel, 2012Different 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 (, 1998A 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, 2009AbstractA 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.
