By improving the conventional electric - arc fusion method , we have realized the splicing between two kinds of mofs and smf with relatively low splice losses . we have written fiber bragg gratings in grapefruit mof successfully . the multi - wavelength resonances are observed in the grating , and theoretical analysis shows that this phenomenon is caused by the resonances between core modes and cladding modes 在此基础上对微结构光纤光栅进行了理论和实验研究,在柚子型光敏微结构光纤上成功写制了布拉格光栅,观察到多波长的反射峰,并利用全矢量有限元方法对微结构光纤布拉格光栅中的多波长谐振现象进行了理论分析,最后在实验上对其在多参量传感和多波长光纤激光器件中的应用进行了尝试。
