In this paper, wavelength conversion based on optofluidic infiltration of photonic crystal fibers (PCFs) is investigated to achieve the suitable wavelength over wide tunable range. For this purpose, two designs of PCFs (the so-called PCF1 and PCF2) with appropriate dispersion properties are simulated, and wavelength conversion via four-wave mixing process for pump wavelengths in both normal and anomalous dispersion regimes is studied. By changing the refractive index [Formula: see text] of the optical fluid infiltrated into the PCF air-holes and then varying the fiber dispersion properties, the converted wavelength region can be tuned. The results show that for the pump wavelength in the normal dispersion regime, the PCF1 infiltrated with [Formula: see text] and PCF2 infiltrated with [Formula: see text] exhibit the maximum wavelength shift. Moreover, the wavelength shift is much higher than that obtained in the anomalous dispersion regime and it can be further increased by increasing the input pump power.

基于光流体渗透光子晶体光纤的可调谐波长转换

在本文中，研究了基于光子晶体光纤（PCF）的光流体渗透的波长转换，以在宽可调范围内实现合适的波长。为此，模拟了具有适当色散特性的两种 PCF 设计（即所谓的 PCF1 和 PCF2），并研究了通过四波混频过程对正常和反常色散状态下的泵浦波长进行波长转换。通过改变渗透到 PCF 气孔中的光学流体的折射率 [公式：见正文]，然后改变光纤色散特性，可以调整转换后的波长区域。结果表明，对于正常色散状态下的泵浦波长，[公式：见正文]渗透的PCF1和[公式：见正文]渗透的PCF2表现出最大的波长偏移。
