a Artist’s impression of the cross-section of the 19-core fiber. b Micrograph of the cross-section of the 19-core fiber. c Infrared camera image of the output facet after 10 m of 19-core fiber when exciting the center core with 3 nm wide ASE centered at 1550 nm. The gray circle indicates the outer edge of the cladding. d Simulated spatial-mode-dispersion vs core pitch Λ. e Simulated spatial-mode-dispersion growth rate vs core pitch Λ. f Simulated spatial-mode-dispersion accumulation with distance.
