Abstract

Water or some other aqueous fluid is employed as the light transmitting medium of a liquid core fiber-optic waveguide cell by employing, to define the core region, a waveguide vessel having an exterior coating composed of a material having a refractive index of less than 1.33. The light conducting channel defined by the aqueous fluid filled core may be a capillary or other suitably shaped vessel.
