1. A micro-structured optical fibre for transmitting at least a predetermined wavelength of light, said optical fibre having an axial direction and a cross section perpendicular to said axial direction, said optical fibre comprising:

  • a core region having a multiplicity of spaced apart core features that are elongated in the fibre axial direction and disposed in a core material, said core region having an effective index of refraction Nco, a cladding region surrounding said core region, said cladding region comprising a multiplicity of spaced apart cladding features that are elongated in the fibre axial direction and disposed in a first cladding material, and said cladding region having an effective index of refraction Ncl, wherein a plurality of said cladding features have a cross-sectional dimension perpendicular to said axial direction being larger than said predetermined wavelength.
