Abstract
A light guide is disclosed and includes a flexible elongated tube having an inner surface and first and second ends. A non-supercritically dried hydrophobic aerogel film is affixed to the inner surface of the tube as a cladding layer, and a fluid core is disposed within the tube. The fluid core has a refractive index greater than the refractive index of the aerogel cladding film.
