This work reports optical functionality contained in, as well as and produced by, thin film coatings. A sol-gel process, formulated with precursor active ingredients of erbium oxide and tetraethylorthosilicate (TEOS), was used for spin-coating thin (∼130 run) erbium-doped (∼6 at. %) silica films on single-crystal silicon. Annealed films produce infrared emission in the 1.5-μm band from erbium ions in the film, as well as greatly enhancing (∼100X) band-gap emission from the underlying silicon. The distinctly different mechanisms for the two modes of optical activities are interpreted in terms of optical emission theory and modeling; prospects for optoelectronic applications are discussed.
