Abstract

Optical waveguides are fabricated in glass-ceramic materials utilizing an ion-exchange process to pattern the waveguide at a temperature below the ceramming temperature of the glass-ceramic material. The optical waveguides may include optically-active dopants dispersed preferably within the crystallite phase of the glass-ceramic material.
