    Chalcogenide glass integrated microresonators (chalcogenide microresonators) have attracted great attention in nonlinear integrated photonics in recent years because of their high linear refraction index, high nonlinearity coefficient, ultra-wide transmittance window, low thermo-optic coefficient, and precisely regulated dispersion with conventional semiconductor micro-nanofabrication technology. Recently, the researchers from the Sun Yat-sun University developed a novel chalcogenide glass (Ge25Sb10S65) material platform and realized a series of high-quality chalcogenide integrated photonic devices. The progress of integrated soliton microcombs generation and regulation based on chalcogenide microresonators was reviewed. The integrated chalcogenide microresonators with high-quality factors(Q>106) were achieved by a modified nanofabrication process. Furthermore, mode-locked soliton microcombs with a low pump power and a widely tunable Kerr-Raman comb were achieved by precisely controlling the dispersion , respectively.
