光纤布拉格光栅被写在多芯光纤的所有120个单模芯上。光纤通过在折射率降低的玻璃护套内逐渐变细而连接到多模端口。其结果是一个紧凑的多模“光子灯笼”过滤器与天文光子应用。锥形结构也是一种有效的扰模器。(C)2012美国光学学会
Fiber Bragg gratings are written across all 120 single-mode cores of a multi-core optical Fiber. The Fiber is interfaced to multimode ports by tapering it within a depressed-index glass jacket. The result is a compact multimode "photonic lantern" filter with astrophotonic applications. The tapered structure is also an effective mode scrambler. (C) 2012 Optical Society of America
