A solar reflective fibre having a longitudinal axis, the fibre comprising: a substantially continuous primary portion having a first refractive index; and a plurality of secondary portions, each secondary portion having a second refractive index different from the first refractive index. The primary and secondary portions are arranged to run substantially continuously along at least a portion of a length of the fibre, the primary portion providing a host medium within which the secondary portions are provided. The primary and secondary portions are arranged to constitute a dielectric mirror structure whereby a phase of a plurality of scattered beams of radiation each beam being scattered at one of a plurality of respective interfaces between primary and secondary portions interfere constructively with one another thereby to reduce an amount of radiation transmitted through the fibre. |
