Supercontinuum generation with extended bandwidth and improved purity in graded-index ring-core fiber

In this paper, we numerically investigate the impact of shape factor ( k ) on the mode properties of graded-index ring-core fiber (GIRCF). A 50 mol% Ge-doped GIRCF with shape factor of 2 is devised to generate supercontinuum (SC) carrying orbital angular momentum (OAM) modes, which possesses flat di...

Summary:In this paper, we numerically investigate the impact of shape factor ( k ) on the mode properties of graded-index ring-core fiber (GIRCF). A 50 mol% Ge-doped GIRCF with shape factor of 2 is devised to generate supercontinuum (SC) carrying orbital angular momentum (OAM) modes, which possesses flat dispersion with a minor variation of
