实验证明了一种利用高非线性光纤（HNLF）双折射效应测量微波频率的新方法。对实现可调测量范围和分辨率进行了详细的理论分析。通过对HNLF中互补偏振域干涉仪对的激励，建立了微波频率和幅度比较函数的数学表达式。我们进行了一个概念验证实验。除16 ~ 17.5 GHz外，可实现2.5 ~ 30ghz的频率测量范围，测量误差在0.5 GHz以内。这种方法是全光的，不需要高速电子元件。
We experimentally demonstrate a novel approach for microwave frequency measurement utilizing birefringence effect in the highly non-linear fiber (HNLF). A detailed theoretical analysis is presented to implement the adjustable measurement range and resolution. By stimulating a complementary polarization-domain interferometer pair in the HNLF, a mathematical expression that relates the microwave frequency and amplitude comparison function is developed. We carry out a proof-to-concept experiment. A frequency measurement range of 2.5-30 GHz with a measurement error within 0.5 GHz is achieved except 16-17.5 GHz. This method is all-optical and requires no high-speed electronic components.
