Abstract
Optical waveguides suitable for use in high temperature environments are constructed of a waveguiding body composed of a first crystalline aluminum garnet, which is clad with an epitaxially deposited layer of a second crystalline aluminum garnet. The second crystalline aluminum garnet has a lower refractive index than the first crystalline aluminum garnet.
