    • A waveguide is fabricated by first preparing two waveguide precursor pieces. Each waveguide precursor piece includes a single-crystal substrate, and an epitaxial coating layer of an oxide coating material on the substrate. The oxide substrate material preferably comprises yttrium as a substrate-material cation, and the oxide coating material preferably comprises a coating-material cation selected from the group consisting of ytterbium, thulium, erbium, and holmium. The two substrates are placed together with the coating layers in contact to form a precursor structure. The precursor structure is heated to an elevated diffusion temperature so that the coating layers bond together and the coating materials and the respective substrate materials interdiffuse to form the waveguide having an interdiffused region. A laser beam may be directed through the interdiffused region, while the interdiffused region is optionally optically pumped through one or both of the substrates.

    • The present invention provides a broadband transmitting protective coating (10) including an AlGaP protective layer (14) deposited on an optical substrate (12) and an anti-reflection film (16) deposited on the AlGaP protective layer (14). The coating (10) is suitable for use with typical infrared and broadband optical substrate materials such as germanium or multi-spectral ZnS. In the case of a germanium substrate (12), the anti-reflection film (16), (16a) preferably consists of a single layer of hard carbon or alternating layers of hard carbon and silicon. In the case of a multi-spectral ZnS substrate (12a), the anti-reflection film (16b) preferably consists of layered Al.sub.2 O.sub.3 /TaO.sub.5 /LaF.sub.3 /MgF.sub.2. The protective coating (10) is preferably deposited on the optical substrate (12) by a metal organic chemical vapor deposition process wherein an initial layer of AlP is nucleated on the substrate (12) at a temperature of approximately 400.degree. C. The temperature of the substrate (12) is then raised to approximately 600.degree. C. and a layer of AlGaP (14) is grown on the substrate (12) to a preselected thickness. The AlGaP coated optical substrate (12) is then polished to a desired smoothness. The anti-reflection film (16) is then deposited on the AlGaP layer (14) using an RF chemical vapor deposition process or a thermal evaporation process.
