摘要: A source of optical supercontinuum radiation comprises a length microstructured fibre and pump laser adapted to generate lasing at wavelength. The is arranged receive the wavelength core region cladding which surrounds region. such that location along (a) group index (GI) versus curve having zero crossing (ZCW) velocity dispersion has GI increases for wavelengths away from ZCW includes indices are greater than as well less ZCW; (b) light 2000 nm propagates matched 400 nm; (c) within 200 ZCW.
