摘要
光子晶体光纤(PCF)和普通光纤的熔接损耗主要来源于两光纤模场直径(MFD)的失配。提出了一种小芯径光子晶体光纤和大模场直径普通光纤低损耗熔接的方法。利用熔融拉锥机加热光子晶体光纤来精确控制光子晶体光纤的空气孔塌缩,以增加光子晶体光纤的模场直径,从而降低其与大模场直径普通光纤的熔接损耗。实现了模场直径为3.94μm的光子晶体光纤和模场直径为10.4μm普通光纤的低损耗熔接,最低损耗小于0.2 dB。
The main source of fusion splicing loss between photonics crystal fibers （PCFs） and conventional fibers is from the mismatching of mode field diameters （MFDs） of fibers. We proposed a method to realize low loss splicing between small core diameter PCFs and conventional fibers. Using a fusion taper rig, we controlled hole collapse accurately to enlarge the MFDs of PCFs. As a result, the splicing loss of conventional fiber and PCF with quite mismatch MFDs can be decreased. Using this method a 0.2 dB splicing loss between a PCF with 3.94 μm MFD and a conventional fiber with 10.4 μm MFD was obtained experimentally.
