multi-laser computer

The ultra-small revolution has begun, thanks to scientists who claim to have developed a laser that can communicate in several wavelengths at once on a computer chip, boosting speed.
The on-chip light source will be a key to enabling the simultaneous transmission of multiple data channels either on-chip or between chips in a single optical fibre, each at a different wavelength.

The device, based on high index doped silica glass, is low loss and has a high degree of manufacturability and design flexibility.

And, this makes it an ideal integrated multiple wave length source not just to improve computing power, but for a wide range of applications including telecommunications, high- precision broadband sensing and spectroscopy, metrology, and even attosecond physics, say the scientists.

The findings have been published in the latest edition of the ‘Nature Photonics’ journal.
