摘要
The cladding thickness of trench-assisted multi-core fibers was theoretically and experimentally investigated in terms of excess losses of outer cores. No significant micro-bending loss increase was observed on multi-core fibers with the cladding thickness of about 30 mu m. The tolerance for the micro-bending loss of a multi-core fiber is larger than that of the single core fiber. However, the cladding thickness will be limited by the occurrence of the excess loss on outer cores. The reduction of cladding thickness is probably limited around 40 mu m in terms of the excess loss. The multi-core fiber with an effective area of 110 mu m(2) at 1.55 mu m and 181-mu m cladding diameter was realized without any excess loss.
