热熔融自回流方法制备硫化物玻璃非线性集成光学波导（特邀）

Chalcogenide glass is a good material for the development of nonlinear integrated optical devices. The special physical and chemical properties make chalcogenide glass integrated optical
The preparation of waveguides has become a difficult point of research. The preparation process of chalcogenide glass waveguides is reviewed, focusing on the use of chalcogenide glass
It has good fluidity in the molten state and adopts the process of preparing chalcogenide glass waveguide by hot melting self-reflux method. This method avoids the destruction of the integrity of the sulfide glass film and the corrosion of the photoresist developer on the sulfide glass material can result in high-quality
Inverted-ridge chalcogenide glass waveguide with small mode field area. Experimental tests show that the sulfide glass is prepared by the hot melting self-reflux method.
The waveguide has good third-order nonlinear optical properties and stimulated Brillouin scattering properties. Finally, the development of sulfide glasses using this method has been prospected.
Research directions and prospects of glass nonlinear integrated optical devices and their systems on a chip.
