本文对基于硅-有机混合缝隙波导四波混频（FWM）的波长转换进行了理论研究。与垂直缝隙波导相比，水平缝隙波导具有更平坦的色散。通过控制几何参数，在具有20 nm厚光学非线性层的水平槽波导中获得了最大非线性系数γ为1.5×10 ~（-1）W/cm ~ 2，最小有效模面积A（eff）为0.065 μm ~ 2的结果。在抽运功率为100 mW时，在4 mm长的水平缝隙波导中获得了7.45 dB的波长转换效率。这种低功耗的片上波长转换器在高集成度光路中具有潜在的应用前景。
Wavelength conversion based on four-wave mixing (FWM) in a silicon-organic hybrid slot waveguide is theoretically investigated in the telecommunication bands. Compared with vertical slot waveguides, the horizontal slot waveguide structure exhibits much flatter dispersion. The maximum nonlinearity coefficient γ of 1.5×10⁷ W⁻¹ km⁻¹ and the minimum effective mode area A(eff) of 0.065 μm² are obtained in a horizontal slot waveguide with a 20-nm-thick optically nonlinear layer by controlling the geometric parameters. The wavelength conversion efficiency of 7.45 dB with a pump power of 100 mW in a 4-mm-long horizontal slot waveguide is obtained. This low power on-chip wavelength convertor will have potential applications in highly integrated optical circuits.
