Abstract

The variation of transmitted power through tapered coaxial couplers is presented as a function of the surrounding refractive index. This response allows us to select suitable cladding materials for the tapers that would desensitize their performance to environmental changes. Further, the use of tapers as refractive-index sensors is outlined.
