Abstract
An optical waveguide, radiation emitting device employing the same, and process for fabricating the radiation emitting device are provided. The optical waveguide has a core fabricated of a first material with a first index of refraction and cladding surrounding the core fabricated of a second material with a second index of refraction. The core is an active material which emits radiation at a desired wavelength when pumped with radiation of a predetermined wavelength, and the first material and second material are dissimilar materials, having been separately fabricated and subsequently physically assembled as the waveguide.
