少模光纤长周期光栅双峰谐振及双参量传感
|
摘要
在少模光纤中写制的纤芯LP_(01)模式向纤芯LP_(11)模式耦合的长周期光纤光栅具有双谐振耦合现象,且该双谐振耦合峰随着温度或应变的增加向相反的波段漂移,从理论和实验上揭示了该现象产生的机理,并基于该现象及特性设计了温度、应变双参量传感器。与传统的基于纤芯基模与包层模耦合的长周期光纤光栅传感器相比,该传感器具有折射率不敏感、光谱稳定、灵敏度高等优势。
The phenomenon of dual resonance coupling exists in few-mode long period grating coupled between core modes LP_(01) and LP_(11).The two resonant dips drift to opposite bands as temperature or strain increases.We research the mechanism of dual resonance from theory and experiment,and design a dual-parameter sensor of temperature and strain.Compared with the long period gratings coupled between core fundamental mode and cladding mode,this sensor has the advantages of refractive index insensitivity,spectrum stability,and high sensitivity.
