Fujitsu Labs Develops Photonics Lightsource for CPU Interconnects

Fujitsu Laboratories last week disclosed the development of a compact silicon photonics light source for use in optical transceivers required for optical interconnects between CPUs. Fujitsu leverages a mechanism that automatically keeps the light source's wavelength and the modulator's operating wavelength in sync, eliminating thermal controls and enabling the optical transceivers to be mounted directly in CPU packaging.
