Chalcogenide glass (ChG) has been fabricated into on-chip integrated waveguides owing to its high nonlinear refractive index. However, the systematic research of Ge-Sb-S glass shows that Ge₂₅Sb₁₀S₆₅ glass has greater hardness and stronger resistance to laser damage than other component glasses considered in this study. Additionally, the high nonlinear refractive index of Ge₂₅Sb₁₀S₆₅ glass makes it a suitable base material for on-chip integrated devices. To further verify the application potential of this glass in integrated photonics, a waveguide based on Ge₂₅Sb₁₀S₆₅ glass, with width W = 2 μm and thickness H = 1.4 μm, was engineered for supercontinuum generation (SCG). A monolithically integrated SCG spanning from 870 nm to 2480 nm is obtained, when pumped by a femtosecond laser at a central wavelength of 1.55 μm, with a repetition rate of 1 MHz. The results indicated that the Ge₂₅Sb₁₀S₆₅ glass has great prospects of utilization in on-chip integrated devices for application in optical frequency combs (OFCs) or SCG.

由于其高非线性折射率，硫属化物玻璃 (ChG) 已被制造成片上集成波导。然而，对Ge-Sb-S玻璃的系统研究表明，Ge ₂₅ Sb ₁₀ S ₆₅玻璃比本研究考虑的其他成分玻璃具有更高的硬度和更强的抗激光损伤能力。此外，Ge ₂₅ Sb ₁₀ S ₆₅玻璃的高非线性折射率使其成为片上集成器件的合适基础材料。为了进一步验证这种玻璃在集成光子学中的应用潜力，基于 Ge ₂₅ Sb ₁₀ S ₆₅的波导玻璃，宽度 W = 2 μm，厚度 H = 1.4 μm，专为超连续谱生成 (SCG) 而设计。当由中心波长为 1.55 μm、重复率为 1 MHz 的飞秒激光器泵浦时，获得了从 870 nm 到 2480 nm 的单片集成 SCG。结果表明，Ge ₂₅ Sb ₁₀ S ₆₅玻璃在用于光频率梳（OFC）或SCG的片上集成器件中具有很大的应用前景。
