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.
Plasmon mode lasers; smaller, faster, better. High speed Information Technology (IT) communication is using more and more of our global energy. Energy efficiency of IT hardware can be improved by incorporating small, high performance lasers for short distance optical communication.
