Abstract

Sol-gel glasses doped with semiconductor quantum dots (QDs) potentially are important materials for photonics switching and communication devices. The fabrication and processing of these materials is much simpler and less costly than that of epitaxy semiconductor materials. Recently there has been substantial progress in the sample quality, doping levels, and size distribution of the quantum dots.¹ Waveguide fabrication by ion exchange has been demonstrated, with viable expansion to integrated devices.²
