摘要
随着集成化程度的不断提高,对非线性光波导制备的各种集成光电子器件的研究成为了当前热点。然而,传统基质材料受自身的非线性特性所限,成为制约光波导器件进一步发展的首要问题。介绍了硫系玻璃材料三阶非线性的研究现状。研究表明,硫系原子在强光作用下容易发生电子云畸变,非线性响应时间可达飞秒数量级,且非线性折射率与金属共价键有着重要的关联。从基质种类、制备工艺和非线性应用领域等方面回顾了硫系基质光波导的研究进展。针对目前研究中存在的问题,提出环保型的基质材料、完善的制备工艺和新型的光波导器件将是未来硫系基质光波导的研究方向。
Abstract
With the development of integration technology, all kinds of integrated optoelectronic devices based on nonlinear optical waveguide become current research hotspots. However, the low level of nonlinearity characteristics of traditional substrate materials has been the primary problem for the development of optical waveguide devices. The research status of the third-order optical nonlinearity of chalcogencide glasses is introduced, and the research results show that nonlinear response time can be up to femtosecond, which is attributed to the distortion of chalcogencide atoms under bright light, and nonlinear refractive index has significant correlation with homopolar metallic bond. The research progress of chalcogenide optical waveguides is reviewed on substrate classification, manufacture process and nonlinear application. Considering the existent problems in the current research, it is proposed that the environmental substrate material, perfect manufacture process and new-type optical waveguide devices are the directions of the future study.
