对基于简并四波混频的高非线性亚碲矿混合微结构光纤中的线性相位失配和光信号增益进行了数值模拟。该光纤的纤芯和包层分别由 TeO2-Li2O-WO3-MoO3-Nb2O5 和 TeO2-ZnO-Na2CO3-P2O5 玻璃设计。这种光纤具有很高的非线性，同时色散平坦且接近于零。通过使用短长度的低泵浦功率光纤可以获得高光信号增益和宽带。
The linear phase-mismatch and the optical signal gain in the highly nonlinear tellurite hybrid microstructured optical fiber based on the degenerate four-wave mixing are numerically simulated. The core and the cladding of this fiber are designed by TeO2–Li2O–WO3–MoO3–Nb2O5and TeO2–ZnO–Na2CO3–P2O5glass, respectively. This fiber has high nonlinearity and at the same time the chromatic dispersion is flattened and close to zero. High optical signal gain and broad band can be obtained by using a short length of this fiber with low pump power.
