论文摘要
共振波长，其中光纤模式转换器使用周期性外部扰动的书面形式达到相位匹配，既是关键的设计参数，又是设备参数。但是，到目前为止，已经缺少一种准确预测任何新纤维和光栅写作设备的共振波长的方法。缺少的链接是缺乏直接的实验方法来估计与外部扰动书写后修饰的联运阶段。提出的方法可以根据两种模式干扰和模式转换之间的新数学联系，从一个宽波长范围内从单个实验中进行此估计。使用新方法，已经在0.004的相对误差内预测了针对不同音高和辐照条件的实验测量的共振波长。
The resonance wavelength, where a fiber mode converter grating written using periodic external perturbations achieves phase matching, is both a critical design parameter and a device parameter. However, a method to precisely predict the resonance wavelength for any new fiber and grating writing apparatus has been missing so far. The missing link was the lack of direct experimental methods to estimate the modified intermodal phase after writing with external perturbations. The presented method can make this estimation from a single experiment, over a broad wavelength range, based on a novel mathematical connection between two-mode interference and mode conversion. Using the novel methods, experimentally measured resonance wavelengths for different pitch and irradiation conditions have been predicted within relative errors of 0.004.
