摘　　要：基于多芯光纤的空分复用是解决当前光通信传输容量瓶颈的最有效方法之一,多芯光纤扇入扇出(FIFO)技术是实现多芯光纤空分复用系统的关键,它用于实现单个多芯光纤到多个单芯光纤的光耦合功能。文章总结了近十年来多芯光纤FIFO器件和装置的方法,将它们归纳为熔融、光纤束、自由空间光和三维集成波导4种类型,分析并比较了几种类型器件/装置的制作方法和性能,对未来可广泛应用的技术方向进行了展望。Spatial division multiplexing based on the multi-core fiber has been believed as a promising and effective way to overcome the foreseeable capacity crunch of single mode fiber transmission.Fan-in Fan-out(FIFO)technology for multi-core fiber is the key to realize multi-core fiber space division multiplexing system,which can realize the optical coupling function from single multi-core fiber to multiple single core fiber.In this paper,we summarize the methods of multi-core fiber FIFO devices in the past decade,which includes fused type,fiber bundle type,free space type and three-dimensional integrated waveguide type.The fabrication methods and performance of several types of devices are analyzed and compared.Finally,the technology direction which can be widely used in the future is prospected.
