【摘要】：通過(guò)在實(shí)芯光子晶體光纖的包層空氣孔中填充5CB型液晶,設(shè)計(jì)出了在室溫附近具有高熱調(diào)諧靈敏度的光子帶隙型液晶光子晶體光纖。采用有限元方法研究了光子帶隙隨光纖結(jié)構(gòu)參數(shù)的變化規(guī)律、光子帶隙位置的熱調(diào)諧特性、光纖限制損耗隨包層孔圈數(shù)的變化以及限制損耗的熱調(diào)諧特性。結(jié)果表明,該光子晶體光纖光子帶隙的位置主要由包層孔直徑?jīng)Q定,其限制損耗隨包層孔圈數(shù)的增加而顯著降低;隨著溫度由25.1℃增加至34.8℃,光子帶隙位置和限制損耗曲線均發(fā)生紅移,限制損耗的最小值位置處的平均熱調(diào)諧靈敏度約為10.3nm/℃;在光子帶隙的中心波長(zhǎng)附近,該光子帶隙型液晶光子晶體光纖和相同結(jié)構(gòu)未填充液晶的光纖之間具有高耦合效率。
[Abstract]:By filling the cladding air holes of solid core photonic crystal fibers with 5CB liquid crystals, Photonic bandgap photonic crystal fiber with high thermal tuning sensitivity near room temperature is designed. The variation of photonic band gap with fiber structure parameters and the thermal tuning characteristics of photonic band gap position are studied by finite element method. The change of limiting loss of fiber with the number of cladding holes and the thermal tuning characteristics of limiting loss show that the position of photonic band gap is mainly determined by the diameter of cladding hole. With the increase of temperature from 25.1 鈩，
