Integrated chalcogenide frequency combs (Invited)
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.
