Tiny nanolaser could cut computer energy use in half
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 journalScience 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.
"The nanolaser opens up the possibility of creating a new generation of components that combine high performance with minimal size. This could be in information technology, for example, where ultra-small and energy-efficient lasers can reduce energy consumption in computers, or in the development of sensors for the healthcare sector, where the nanolaser's extreme light concentration can...
