Abstract

The observation of second-harmonic generation and all-optical switching in telecommunications fibers, optical amplification in rare earth-doped fibers, and the demonstration of lasing in rare earth-doped glass channel waveguides have collectively changed the notion of glass as being just a passive material for integrated optics. The diverse range of specifications to which glass properties can be tailored results from, in contrast to their crystalline counterparts, the ability to incorporate very large quantities of dopants and glass modifiers throughout a continuous range of stoichiometries.
