Solve the mystery of invisibility with Harry Potter-style cape!

Washington D.C. [USA] Nov. 9(ANI): Gone are the days when magic of invisibility could only be seen in science fictions, as a recent research has developed a cloaking device for microscopic photonic integrated devices in an effort to make future chips smaller, faster and consume much less power.

The study by University of Utah says that the future of computers, data centers and mobile devices will involve photonic chips in which data is shuttled around and processed as light photons instead of electrons. The advantages of photonic chips over today's silicon-based chips are they will be much faster and consume less power and therefore give off less heat.

The problem, however, is if two of these photonic devices are too close to each other, they will not work because the light leakage between them will cause "crosstalk" much like radio interference. If they are spaced far apart to solve this problem, you end up with a chip that is much too large.

So researcher Rajesh Menon and his team discovered a special nano-patterened silicon-based barrier in between two of the photonic devices, which acts like a "cloak" and tricks one device from not seeing the other.

"The principle we are using is similar to that of the Harry Potter invisibility cloak," Menon said. "Any light that comes to one device is redirected back as if to mimic the situation of not having a neighboring device. It's like a barrier, it pushes the light back into the original device. It is being fooled into thinking there is nothing on the other side."

Consequently, billions of these photonic devices can be packed into a single chip, and a chip can contain more of these devices for even more functionality. And since these photonic chips use light photons instead of electrons to transfer data, which builds up heat, these chips potentially could consume 10 to 100 times less power, which would be a boon for places like data centers that use tremendous amounts of electricity.

Menon believes the most immediate application for this technology and for photonic chips in general will be for data centers similar to the ones used by services like Google and Facebook.

"By going from electronics to photonics we can make computers much more efficient and ultimately make a big impact on carbon emissions and energy usage for all kinds of things," Menon said. "It's a big impact and a lot of people are trying to solve it."

Currently, photonic devices are used mostly in high-end military equipment, and he expects full photonic-based chips will be employed in data centers within a few years.

The study was published online in the latest edition of the science journal, Nature Communications. (ANI)
