Indoor wireless is hitting limits as more devices crowd the same spectrum. Streaming, video calls, and smart home gear are pushing networks harder while power use rises. A new class of laser chips offers a different path by moving data onto light.
Researchers built a chip-scale optical link that delivers ultra-fast indoor connections with lower energy use. Instead of broadcasting signals widely, it sends data through controlled infrared beams, opening more usable capacity while avoiding interference in dense spaces.

At the core is a chip with 25 microscopic lasers, each carrying its own stream. Working in parallel, they push throughput far beyond a single source. In testing, the setup reached more than 360 gigabits per second across a short indoor link.
The gains are not just speed. Power use drops significantly, offering a more efficient way to handle rising demand.
