| 摘 要： | 为了研究机械感生长周期光纤光栅 (MLPFGs) 的特性,利用机械微弯法写制了长周期光纤光栅.采用机械先加工技术制作了周期性压力槽,通过设计机械写制结构,制作了MLPFGs,并实验验证了周期性压力槽的周期、周期数以及外加应力等参数与MLPFGs透射谱的关系.最后, 研究了温度对带有涂敷层和无涂敷层单模光纤写制的MLPFGs的影响.实验表明:MLPFGs的最大谐振峰值可达16 dB,插入损耗＜0.5 dB; 通过改变压力槽的周期,实现了谐振波长＞14 nm的调谐范围;带有涂敷层和无涂敷层单模光纤写制的MLPFGs谐振波长的温度灵敏度分别为 0.057 nm/℃,0.086 nm/℃,谐振峰值的温度灵敏度分别为 0.230 dB/℃,0.312 dB/℃.该写制结构能较好地控制MLPFGs的透射谱,同时结构简单、易擦除、成本低,在光纤传感领域具有一定的应用价值.

| Abstract: | With the aim to study the characteristics of Mechanically Induced Long-period Fiber Gratings(MLPFGs),the MLPFGs are fabricated based on the micro-curve principle.The grooved plates are made by the mechanical line processing technology and the MLPFGs are fabricated by pressing a plate with periodic grooves against a short length of fiber.Then,the relationship between MLPFG spectra and fabricated parameters,such as groove periods,period numbers,and pressures are studied.Finally,the influences of the temperatu... |
