In this work, we report the effect of four-wave mixing (FWM) in MoTe₂ deposited on a side-polished fibre (SPF). The MoTe₂ layer has a nonlinear coefficient of 17.368 W⁻¹ km⁻¹ at 1550 nm, while the coated SPF has a conversion efficiency of – 38 dB and output tuning range of 5 nm. The generated idlers from the induced FWM effect were observed to be highly stable with minimal peak fluctuations and only minor changes in their measured conversion efficiency. The proposed MoTe₂ based SPF is thus a suitable device for inducing the FWM effect in an optical fibre laser cavity and could also serve to induce other non-linear optical effects for use in optical communications networks.

在这项工作中，我们报告了沉积在侧面抛光纤维（SPF）上的MoTe _2中的四波混频（FWM）的影响。MoTe ₂层在1550 nm处的非线性系数为17.368 W ^-1 km ^-1，而涂覆的SPF的转换效率为– 38 dB，输出调谐范围为5 nm。观察到的是，由诱导的FWM效应产生的惰轮是高度稳定的，具有最小的峰值波动，并且它们测得的转化效率只有很小的变化。因此，所提出的基于MoTe ₂的SPF是在光纤激光腔中引起FWM效应的合适设备，并且还可以引起在光通信网络中使用的其他非线性光学效应。
