Spectrogram animation, 15.5 µm core separation Aku Antikainen Govind Agrawal 10.6084/m9.figshare.9730568.v1 https://opticapublishing.figshare.com/articles/media/Spectrogram_animation_15_5_m_core_separation/9730568 The total spectrogram over all cores of a hexagonal seven-core fiber at various propagation distances. The cores have a diameter of 6 µm and are separated by 15.5 µm. The input pulse is a 15 kW 100 fs sech-pulse launched in the center core. 2019-10-01 18:26:55 Fiber Optics Nonlinear fiber optics Supercontinuum multi-core fiber
