Abstract Information technology has an increasingly strong demand for high-speed and
large-capacity optical fiber networks. Space division multiplex (SDM) is a new generation of …

In order to reduce the fiber crosstalk for the space division multiplexing (SDM), this paper
proposes a novel multi-core few-mode fiber of composite refractive index profile and dual …

This paper proposes a novel 7-core 5-mode fiber with large mode area and low inter-core
crosstalk (XT). The proposed optical fiber, by adopting a combination of air-trench structure …

A kind of bending-insensitive multicore fiber (MCF) is proposed. The core adopts a low-
mode gradient index structure to form a seven-core few-mode fiber. The finite element …

The multi-core few-mode fiber based on space division multiplexing technology is one of the
critical ways to address the issue that the current single-mode fiber communication capacity …

The approach for homogeneous core structure design and selection based on low crosstalk,
low dispersion, and acceptable mode effective area have been explored. The forward and …

A novel trench-assisted dual-mode multi-core fiber with large-mode-field-area is proposed.
The structure consists of 17 conventional cores and two air holes according to a regular …

This essay designed a kind of new seven-core fiber with lower crosstalk and loss, and made
space division multiplexing transmission experiment based on this seven-core fiber. It is …

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 …

We propose a seven-core five-mode fiber with air hole-assisted and high refractive index
ring structure, and it can be fabricated by the stack-and-draw technique. The air hole …
