摘要
提出了一种单模光纤(SMF)与毛细管光纤耦合的有效方法,研究了两种不同结构毛细管光纤与单模光纤的耦合问题。通过对单模光纤与毛细管光纤熔点处进行熔融拉锥实现了单模光纤与毛细管光纤之间的高效耦合。对该耦合方法的耦合机理及耦合光传输特性进行了研究、对比,并通过实验对理论预测进行了验证。该耦合技术具有简便易行、耦合效率高的特点。
An effective linking and coupling method for single core single mode fiber （SMF） and capillary optical fiber is proposed. Two types of capillary optical fiber which have different structures are investigated. By splicing and tapering at the fusion point of single mode fiber and capillary optical fiber, an effective bi-tapered fiber coupling technique is implemented. The coupling mechanism and the transmission properties are studied and compared. The theoretical prediction is confirmed by the experimental results. The coupling approach is simple and efficiency.
