1. A method of fabricating a ceramic waveguide, the method comprising:
reacting an organic precursor, at least one transition metal complex, and a plurality of rare-earth metal complexes to form a plurality of rare-earth doped crystalline nanoparticles;
sintering the plurality of rare-earth doped nanoparticles to form a doped polycrystalline ceramic substrate;
disposing a transition metal ceramic slurry over the doped polycrystalline ceramic substrate; and
sintering the slurry to bond the transition metal ceramic to the doped polycrystalline ceramic substrate.
