Research progress of third-order optical nonlinearity of chalcogenide glasses
Résumé
Chalcogenide glasses (ChGs) are a promising candidate for applications in nonlinear photonic devices. In this paper, we review the research progress of the third-order optical nonlinearity (TONL) of ChGs from the following three aspects chemical composition, excitation condition, and post processing. The deficiencies in previous studies and further research of the TONL property of ChGs are also discussed.
