Intel demonstrates silicon laser
News Intel has devised a laser out of silicon, the latest in a series of steps that could take the expense and pain out of optical communication. Technically, silicon in the experimental laser does not generate the light beam -- a separate beam does...

Intel 'peels onion' with nanosurgery
News In the age of sub-micron, half-billion part single chips, the techniques are exactly the same -- but instead of probes, you use laser beams and infra-red microscopes that can see though silicon, and soldering in new parts involves carving micron...

IBM saves chipmaking kit from an early bath
News Laser light shining through an intricate mask throws a microscopic shadow pattern onto the wafer, which then becomes permanent through chemical processes similar to the process in which a negative becomes a photographic print.

Nano-nose sniffs out smallest scents
News Tiny gold-coated silicon bars two microns long and fifty nanometres thick were vibrated by heating them with a solid-state laser at around two million times a second, and variations in their resonant frequency measured.

Intel gets optical with fibre
News The company recently showed off a silicon modulator that chops up laser light into 1s and 0s. Intel is trying to remove some of the inherent difficulties of optical technology by making as many of the components as possible on standard silicon wafers.
