New light-based computer chip is 15 times faster than electricity-based chip

Light-based microprocessor chip

The future is poised to welcome computer chips that have very high speed and consume as little energy as possible. Taking us into that future, researches at MIT, the University of California, and the University of Colorado, have developed a microprocessor chip that uses light instead of electricity to transfer data at immensely fast speed consuming very little amount of electricity.

You’d know the laptops and computers we own have microprocessors that use electricity to transfer information; this new computer chip would enable transfer of data through photonics – light based technology. Using light for transferring data means lesser energy is consumed by the processor.

The newly developed microprocessor chip measures 3mm by 6mm and it has a bandwidth density of 300GB per second per square millimetre, which is approximately 15 times faster than its electrical counterparts.

Vladimir Stojanović, associate professor at the University of California said,

This is a milestone. It’s the first processor that can use light to communicate with the external world.

Describing the future of chip, Vladimir’s colleagues Miloš Popović said,

Light based integrated circuits could lead to radical changes in computing and network chip architecture in applications ranging from smartphones to supercomputers to large data centers.

According to the developers, the chip, slated to pave way for faster and more powerful computing can be integrated into the current processing system most easily.
