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 and wavelength conversion.English200710.1109/COINACOFT.2007.4519076http://www.scopus.com/inward/record.url?scp=51349137875&partnerID=8YFLogxK
