Intel researchers build laser on chip.

Working with the basic material of computer chips, Intel researchers have constructed an all-silicon laser that could lead to computers one day harnessing light waves rather than electrical currents to shuttle data swiftly. Today, lasers that power fast optical networks require exotic - and expensive - materials and are mainly used in vast communications networks. With everyday silicon, the capacity and efficiency of light waves could be used cheaply in much smaller environments. (Boston.com)
