Abstract

We describe and explain the design methods for the cores, trench layers and core number in multi-core fibers (MCFs) in detail. According to such method, we propose relative optimized design schemes for heterogeneous trench-assisted multi-core fiber (Hetero-TA-MCF), inside which cores are arranged in one-ring structure. This Hetero-TA-MCF is a kind of bend-insensitive MCF with high density of cores and ultra-low crosstalk.
