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. The light emitting device employing the optical waveguide is configured either as an amplified spontaneous emission (ASE) source or laser source employing appropriate reflective materials at the ends of the optical waveguide.
