Teaching old dogs new tricks: making ordinary glass both guide and modulate light in photonic chips. The continued revolution of telecoms, and other industries, by photonics demands active integrated photonics: chips that can switch, modulate and modify light. Currently this requires problematic materials. This project will innovatively combine breakthroughs in two areas: poling and laser writing, to produce active devices in standard silicate glass chips.
