摘要：
A photonic crystal fiber (10) comprising a core region and a cladding region surrounding the core region. The core region and the cladding region comprise a material (12) having a first refractive index, the cladding region additionally comprising a plurality of microstructures (14) extending from an input end of the fiber along a longitudinal axis of the fiber to an output end of the fiber, the plurality of microstructures (14) having a second refractive index which less than the first refractive index. The plurality of microstructures in the cladding region are arranged in a cross-sectional pattern comprising at least one ring of microstructures surrounding the core region, wherein a diameter of the core region Dcore is at least 16 µm, the photonic crystal fiber having a transmission bandwidth of 200 nm or more.
