摘要
基于倏逝波理论，利用熔融拉锥技术，采用多种光纤，研制出了一种可以用于激光集束的多芯的全光纤器件。这种器件具有插入损耗小和器件芯间平行度高等优点。现已研制成功 19芯和 37芯光纤集束器，插入损耗＜1 dB。这种新型光纤器件为光纤放大网络(FAN)集束提供一体化的阵列集束光纤，提高空间利用率，便于在大规模使用光纤的环境中应用。
Abstract
Based on the theory of evanescent wave，a muliti-core all fiber device is investigated with kinds of fibers by fused biconical taper technics，which can be used for laser beam combination. The insertion loss of the fiber device is smaller，and the fiber coreparallelism is better. The devices of 19 and 37 fibers have been successfully manufactured. The insertion loss of the device is less than 1 dB. The new fiber device provides fiber amplification network an integrated fiber bundlearray，thatimprovesthespaceutilizationandisconvenientfortheapplicationofthelargescalefiberenvironment.
