The Technical University of Denmark (DTU) has developed a nanolaser that could facilitate on-chip data transmission using photons, allowing thousands of these devices on a single microchip. This advancement may enhance device speed while cutting energy consumption by 50%.

The nanolaser is based on III-V semiconductor materials with a quantum well active region, utilizing topology optimization for its cavity design. Key applications focus on creating efficient on-chip optical interconnects to reduce energy dissipation from electrical connections. The next goal is to demonstrate electrically driven nanolasers with high quantum efficiency within the next five to ten years.
