A lasing germanium

News: Communications    February 5, 2010
Germanium, a semiconducting element, is not supposed to lase. That is, when it gets its electrons excited, they go flying off as heat – not light. So the conventional wisdom in microelectronic circles (and textbooks) is that germanium does not lase – and can’t be made to work in a laser. This was unfortunate, because [...]

Excited quantum dots may lead to photonic computers

News: Computer Power    January 19, 2010
The push for faster computers…more powerful computers however that is defined…proceeds along several lines: Traditional (in silicon semiconductors), quantum (several forms of quantum computing), biological (based on organic chemistry), and optical (using photons of light instead of electrons). Almost every year advances are made along each line of research. Eventually the advances will add up [...]
