The light includes a laser (), which operates at or near its fundamental wavelength and produces pulses of a duration longer than 0.5 ns, and a micro-structured optical fibre () arranged to guide the pulses, wherein the light is generated by the pulses in the fibre (). The light source may e.g. be useful in applications such as spectral testing of fibre components and spectral analysis of chemical and biological samples.

Broad spectrum light source

A holey optical fibre for supporting propagation of light of a wavelength &#x3bb;,comprises a plurality of cylinders () each having a longitudinal axis, the cylinders () being separated from each other by regions of a matrix material () and having their longitudinal axes substantially parallel to each other. Each cylinder () has a diameter, in the plane perpendicular to the longitudinal axis, that is small enough for the composite material of the ensemble of cylinders and matrix material to be substantially optically homogenous in respect of light of wavelength &#x3bb;.
