Nanochannel glass materials have the potential for numerous nanophotonic applications. Features as small as 10 nm can be created in an optically transparent glass matrix, in a large array format. Complex patterns can also be generated. The ability to fabricate complex optical structures at the nanoscale enables opportunities for new device fabrication and an ability to explore optical interactions at dimensions on the order of a wavelength or smaller. The fabrication, characterization and utility of nanochannel glass materials will be described.
