Light vs. Electrical Signals

Earlier today IBM issued a press release detailing the use of photons in-place of electrons in the new 90nm CMOS chip design. This new 'nanophotonic' chip with lay the ground work for creating faster and lower cost chips for the next 10 years, if not longer.  This new design has increased bandwidth to 25Gbps, using light signals, and in turn will eliminate bottle necking in current systems. This design will also allow terabytes of data to be transferred between distant parts of the computer at light speed, hehe.
