Micro/nano-optical devices are some optical devices which have micro/nano-scale size， and they have some advantages，such as small volume，high reliability，high coupling efficiency，light weight，flexible design and easy integration. As a novel substrate material of micro/nano-optical device，chalcogenide glass possess some unique advantages， such as large infrared transmission window， ultrahigh nonlinear coefficient， smaller two photon absorption coefficient， ultrashort nonlinear response time and tailorable compositions. In recent years，chalcogenide glass micro/nano-optical devices have attracted many attentions. The research progress of chalcogenide glass micro/nano-device is reviewed in terms of chalcogenide glass micro/nano-fiber， microsphere，photonic crystal and microring.Their potential applications and development prospects are also discussed.

Compared with silica glass,chalcogenide glasses possess high refractive indices (2.0~3.5), low photon energies (lower than 350 cm-1), wide infrared transmission window, larger nonliner refractive indices and particular photoinduced properties. Chalcognide glass based micro-nano photonic devices have attracted so much attention. The research progress of chalcognide glass based micro-nano photonic devices are reviewed in terms of fabrication, property and application of devices. The current situation of the study from several research institutions is summarized and stated. Their further development prospect is also discussed.
