Raj Dutt, an IIT-Kharagpur alumnus and Chairman and CEO of APIC Corp and Photonic Corp in the US, has developed a next-generation energy-efficient computer chip that helps computer processors consume up to 90 per cent less energy and run up to 60 per cent faster.
The significance of the breakthrough technology is that information transfer on the semiconductor chip as well as between components, will now be done using light – photons – instead of just electrons. Photons do not generate heat, thus thy do not need to be cooled. For electronics, cooling is one of the largest cost components. Photonic interconnects do not generate heat and use less size than electronic copper interconnects, so more transistors can be put onto a chip.
The US Department of Defence is fully supporting Dutt’s new technology in view of its potential. In fact, the Pentagon is testing the chip’s application in the ambitious F-35 Joint Strike Fighters.
