In this work, we report the use of V₂C-deposited SPF as a nonlinear device for the generation of four-wave mixing (FWM) effect in 1.5- and 2.0-µm wavelength operation. The FWM-based system was able to generate idlers at 1.5- and 2.0-µm with a peak conversion efficiency of –44 dB and –41 dB and had a maximum tuning range of 5.5 nm and 12 nm respectively. The nonlinear optical properties of V₂C MXene were studied by Z-scan analysis, where V₂C had a nonlinear absorption coefficient, β and nonlinear refractive index, n₂ of (5.95 ± 5.18)$\times$10^-8 m/W and (-2.43 ± 4.93)$\times$10^-20 m²/W. The experimental results demonstrated that V₂C-deposited SPF was effectively employed as a nonlinear device to induce the FWM effect.

在这项工作中，我们报告了使用 V ₂ C 沉积的 SPF 作为非线性设备在 1.5 和 2.0 微米波长操作中产生四波混合 (FWM) 效应。基于 FWM 的系统能够产生 1.5 微米和 2.0 微米的闲散光，峰值转换效率为 –44 dB 和 –41 dB，最大调谐范围分别为 5.5 nm 和 12 nm。通过Z扫描分析研究了V ₂ C MXene的非线性光学特性，其中V ₂ C具有非线性吸收系数β和非线性折射率n ₂ (5.95±5.18)$\times$10 ^-8 m/W 和 (-2.43 ± 4.93)$\times$10 ^-20 m ² /W。实验结果表明，V ₂ C 沉积的SPF 被有效地用作非线性装置来诱导FWM 效应。
