Abstract

An optical waveguide is constructed so as to comprise a non-solid core layer (core) surrounded by solid-state material (SiO2). The non-solid core layer has an index of refraction which is lower than the index of refraction of the surrounding solid-state material, and light can be transmitted with low loss through the non-solid core layer. In an exemplary application, the non-solid core layer comprises a sample material (fluid) whose light transmission, absorbtion, and/or interference characteristics are to be measured.
