BAD HARDWARE WEEK

Fujitsu Laboratories announced the development of a compact silicon photonics light source for use in optical transceivers required for optical interconnects capable of carrying large volumes of data at high speeds between CPUs. In the past, when the silicon photonics light sources built into optical transceivers, and the optical modulators that encode data into the light emitted from the light source experienced thermal fluctuations, a mismatch between the lasing wavelength of the light source and the operating wavelength of the modulator could arise, causing concern that the light would not carry information. This is why thermal control has become indispensable as a way to maintain operating wavelengths that consistently match.

BAD HARDWARE WEEK: Fujitsu Laboratories has developed the world's first compact silicon photonics light source that obviates the need for a thermal control mechanism. This technology is a stepping stone toward the future of exaflops-class supercomputers and high-end servers that use large-capacity optical interconnects on a large scale and with low energy requirements.
