GoKawiilDTU researchers unveil nanolaser that could halve computer energy use
Scientists at the Technical University of Denmark built a nanolaser small enough to potentially be embedded by the thousands on a single microchip, letting devices transmit data as light rather than electrical signals. The work, led by professor Jesper Mørk with colleagues Meng Xiong and Yi Yu, appeared in Science Advances.
GoKawiil's interpretation of the reporting above, not reported fact.
Electronic circuits inside chips waste energy as heat and cap how fast data can move, while fiber-optic light already carries most internet traffic efficiently between locations. Bringing that same optical efficiency directly onto chips could cut computer energy consumption by roughly half, according to Mørk, while also enabling more sensitive medical sensors and imaging tools.
- DTU built a nanolaser compact enough for mass integration onto microchips
- Optical, light-based data transfer on chips could cut energy use by up to 50%
- Beyond computing, the tech could improve biosensors and high-resolution medical imaging
Cable Matters 10Gbps Active Optical USB Cable — Photonic data transfer isn't just a lab dream inside these active optical cables, light already carries your data instead of electrons. It's a fun, tangible way to experience the same idea DTU's nanolaser is scaling down to chip size, and it keeps long runs fast without bulky copper.
