Researchers have developed the world’s most narrowband diode laser on a chip. This laser represents a breakthrough in the fast-growing field of photonics, and will bring applications like 5G internet and accurate GPS closer. We are slowly reaching the bounds of what is possible with electronics. That is why scientists and the private sector are committed to photonics – a key technology that makes numerous other innovations possible. This involves the deployment of photons (light particles) for transporting and processing data.

For photonic chips to function as efficiently as possible, one has to be able to properly control the light signals...
