Abstract: Chalcogenide glasses offer large ultrafast third-order
nonlinearities, low two-photon absorption and the absence of free carrier
absorption in a photosensitive medium. 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,
