Inverse design optimization for efficient coupling of an electrically injected optical antenna-LED to a single-mode
Abstract:
Efficient high-speed nanoscale optical sources are required for low-power next-generation data communication. Here we propose an integrated antenna-LED on a single-mode optical waveguide. By leveraging inverse design optimization, we achieved a waveguide coupling efficiency of 94% and an antenna efficiency of 64%, while maintaining a high average enhancement of 144 - potentially enabling >100GHz direct modulation.
