Fiber optics enable data communication at the speed of light. But the amount of data that can be sent along any fiber optic is limited by the amount of information you can encode in the wave wave wave traveling through it. At present, fiber optic technology uses many different light properties to encode information, including brightness, color, polarization, and propagation direction.
But if we want to fill even more information through fiber optics, we need to use other light attributes to encode more information without disturbing the properties used today. Such a feature could help increase the bandwidth of fiber optic technology, including internet speeds.
If the light wave passing through the optical fibers rotates helically – like a spring – then it has an angular momentum, and in fact it helps to measure the momentum when it rotates around a point. But there was a major problem with the use of angular momentum for the decoding of information from fiber optics. We needed a material with microscopic helical nanoscale structures that could detect bundles of twisted light.
A new research shows how we can control the angular momentum of light at nanoscale using an integrated nanofutton chip. So, for the first time, we have a chip with a number of ornate nano-openings and nano-grooves that allow the on-chip to manipulate the twisted beam beams.
The helical design of these microscopic openings and grooves removes the need for any other bulky optics with interference to detect the angular momentum signals. And here the solution to the problem is called nanofutton chip.
So, for example, if we send a data signal with a nanofutton chip, which is essentially a microchip that uses light instead of electrons, it will help us with great accuracy knowing where the data is going, otherwise information will be lost.
Using our nanofuff chips, we can accurately direct the angular momentum signals without losing the information they carry. In addition, the angular velocity information of many different signals can be simultaneously processed by the chip. This means we can achieve an extremely large bandwidth, with six times more access to data than the current technology used today.
Due to the rapid development of nanotechnology, there is practically no major technical challenge to prevent mass production of this chip today. This discovery opens up a whole new perspective on the use of light to generate chip information, to transmit and retrieve images, videos, sounds and so on.
It could be used in applications such as data transmission, on high definition screens, in ultra-high-capacity optical communications. However, the main element is that it provides extremely secure optical encryption, one of the most serious issues on the Internet, since hackers are free to decrypt and decrypt encrypted information.
Since the chip is comprised of a series of independently controlled units and each individual unit is capable of independently processing the angular momentum information, this chip arrangement allows the parallel processing of visual information.
A large number of optical fibers in a fiber bundle can be processed through the chip in parallel, which means that the processing speed can be significantly increased considering how large the device is. The present methodology described above will lead to significantly higher internet speeds along with a number of other useful applications.
