has caught the attention of the Pentagon, which is testing its application in the ambitious F-35 Joint Strike Fighters.

The breakthrough technology by Dutt, Chairman and CEO of privately-held APIC Corp and Photonic Corp, helps computer processors consume up to 90 per cent less energy and run up to 60 per cent faster.

"The significance of the 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 (electronics)," California-based Dutt said.

There are many advantages in size, weight and especially power consumed, he explained during his recent trip to Washington, where he met Finance Minister Pranab Mukherjee.

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. Most significantly, we have figured out how to do this using the same economical process used in manufacturing semiconductor chips today, enabling them to be stamped out by the millions," Dutt said.

Well aware with the potential of the computer chip, the US Department of Defence is fully supporting Dutt and his company. The Pentagon is testing the chip's application in the ambitious F-35 Joint Strike Fighters.
