Tiny nanolaser could cut computer energy use in half

Researchers at DTU have developed a nanolaser that could enable microchips to transmit data using light instead of electricity. This innovation promises to significantly increase computing speeds while reducing energy consumption by up to 50%.
Why it matters
Improving energy efficiency in data centers and consumer electronics is vital for reducing the environmental footprint of the rapidly growing digital economy.
The development of a nanolaser could mark an early step toward a future in which microchips communicate entirely with particles of light.
Researchers at DTU have created a tiny nanolaser that could eventually help make computers, smartphones, and data centers faster while using much less energy. The breakthrough was published in the scientific journal Science Advances .
In the future, thousands of these lasers could potentially be integrated onto a single microchip. Instead of moving information around a chip with electrical signals, devices could transmit data using photons, the particles that make up light.
