1. A source for supplying light, the source comprising:
a broad band source configured to generate broad band light pulses; and
a microstructured delivery fiber having a longitudinal axis, an input end for launching light and a delivery end for delivering light, the microstructured delivery fiber comprising a core region and a cladding region surrounding the core region, wherein the core region has a diameter of up to about 15 μm and the cladding region comprises a cladding background material having a refractive index Nbg and a plurality of inclusions of solid material having refractive index of up to Ninc and extending in the direction of the longitudinal axis of the microstructured delivery fiber, wherein Ninc<Nbg and the plurality of inclusions in the cladding region is arranged in a cross-sectional pattern comprising at least two rings of inclusions surrounding the core region, the microstructured delivery fiber having a transmission bandwidth of about 200 nm or more;
wherein the microstructured delivery fiber is arranged for receiving at least a portion of the broad band light pulses for delivering at least a part of the received portion of the broad band light pulses.
