This unique combination of properties is nearly ideal for all-optical signal processing devices. In this paper we review the key properties of these materials, outline progress in the field and focus on several recent highlights: high quality gratings, signal regeneration, pulse compression and wavelength conversion.17 pages"OSA will grant the authors permission to deposit the publisher’s pdf from their Optics Express articles into the repository with the proper citation (reference number or journal /volume/page/year citation)." - from email received from Authorized Agent, The Optical Society, 27/05/10generalnonlinear optics, fibersnonlinear optics, integrated opticsultrafast nonlinear opticswaveguides, planarultrafast processes in fibersUltrafast all-optical chalcogenide glass photonic circuits2007-07-1210.1364/OE.15.0092052015-12-08
