摘要

我们提出了通过添加不同厚度的氧化碲(TeO2)顶层包层来优化非线性参数的氮化硅(Si3N4)波导设计。所提出的波导计算出的非线性参数是化学计量氮化硅的5倍，并且在近红外波长表现出异常的群速度色散。

Optimization of Nonlinear Optical Properties of Tellurium-Oxide-Coated Silicon Nitride Waveguides

We propose designs of silicon nitride (Si3N4 waveguides with optimized nonlinear parameter by addition of tellurium oxide (TeO2) top-cladding layers of various thicknesses. The proposed waveguides have calculated nonlinear parameters of up to five times that of stoichiometric Si3N4 and exhibit anomalous group velocity dispersion at near infrared wavelength.
