Abstract :
Chalcogenide glasses offer large ultrafast third-order nonlinearities, combined with low two-photon absorption and absence of free carrier absorption in a photosensitivity medium. We review the key properties of these materials, including the strong photosensitivity and focus on several recent demonstrations of ultra-fast all-optical signal processing: optical time division multiplexing, all-optical signal regeneration and wavelength conversion.
