Problem Addressed

On-chip optical communication and data processing has received significant interest as part of a drive to develop ever higher-performing computers. One major technological hurdle in the development of optoelectronic devices needed to bridge optical and electronic computing platforms is the lack of light sources that are simultaneously capable of ultra-fast modulation and amenable to on-chip integration. Conventional light-emitting diodes suffer from low modulation speeds while the large form factor of electrically driven lasers preclude on-chip integration. This invention proposes a novel design for an optical nanoantenna that meets both speed and on-chip integration requirements.
