光子晶體光纖,又稱為微結(jié)構(gòu)光纖或多孔光纖,其主要特征是沿光纖長度方向,在純石英基底材料上周期性排列著二維的貫穿孔洞或摻雜區(qū)。 由于光子晶體光纖的結(jié)構(gòu)特點,需要采用特別的制作工藝,例如毛細(xì)管堆積法,這極大拓展了光纖在設(shè)計和制作上的自由度。光子晶體光纖結(jié)構(gòu)的種類多,纖芯或包層中空氣孔間距、大小與幾何形狀都會對光子晶體光纖的特性產(chǎn)生重要影響。 北億纖通致力于該系列光纖產(chǎn)品的研究與開發(fā),基于合成原材料、FCVD工藝,通過理論模擬計算,開發(fā)出無截止單模光子晶體光纖、保偏光子晶體光纖、光敏光子晶體光纖、高非線性光子晶體光纖、布拉格包層光纖及空芯光子晶體光纖產(chǎn)品。
