“Complementary metal-oxide-semiconductor (CMOS) technology has provided a highly sensitive detection platform for high-resolution optical imaging, sensing and metrology. Although the detection of optical beams carrying angular momentum have been explored with nanophotonic methods, the metrology of optical angular momentum has been limited to bulk optics. We demonstrate angular-momentum nanometrology through the spatial displacement engineering of plasmonic angular momentum modes in a CMOS-compatible plasmonic topological insulator material.”
Twisted Light Could Dramatically Boost Data Rates

“Big deal, you say? It most certainly was. The concept of orbital angular momentum (OAM) has done nothing less than inspire a reimagining of what we’re capable of doing with electromagnetic radiation. Beams that carry OAM can be used to move tiny objects, and they have been used to enhance the resolving power of microscopes.”

“One measure is the amount of information that courses through it: about five exabytes a day. That’s equivalent to 40,000 two-hour standard definition movies per second.It takes some wiring up. Hundreds of thousands of miles of cables criss-cross countries, and more are laid along sea floors to connect islands and continents. About 300 submarine cables, the deep-sea variant only as thick as a garden hose, underpin the modern internet. Most are bundles of hair-thin fibre optics that carry data at the speed of light.”

I've never heard the term twisted light before. That's just how EM waves propagate. Twisted light suggests "not twisted light" is normal light. However: All light is "twisted" in one way or another. Only for the very special case of E and H Field components in phase with each other "not twisted" light exists. Ps. We are "decoding" (as it was called in this video) EM waves just the way described in this video just for much lower frequencies. The innovation now is that we may soon be able to do it in the Terra Hz range, which previously wasn't feasible in standard conditions.Currently for EM waves in very high Frequencies (aka light) we usually use pulses of monofrequent carrier waves. That means we are only using information of the time domain. What we are trying to do is using light of a range of carrier frequencies. That allows us to use information from the frequency domain.

[@BBBrasil]

Amazing video, amazing Maren. For the sake of explanation, the video dumbed down a little too much some tech talk. We can typically transmit 80 optical channels in one single fiber. The OAMM might allow us to squeeze more into that fibre. All those channels are in the infrared side of the spectrum, to use visible light or ultraviolet we cannot use common fiber. This typically means a backbone transmission between communication hubs, not end user access, but it might allow for more light channels to reach a neighborhood or even a street, providing faster speeds per end user / subscriber.

[@thor-andersaagesen3934]

I work with fiber optics, and i don’t see how this differs that much from current technology. Using different wavelengths of light in the same fiber optic cable is already a thing, we just need filters in each end to merge and split the wavelengths. Does this new technology just offer a way to merge more wavelengths together? Also, as far as i know, visible light isn’t used in fiber optics as you say. I certainly haven’t seen any visible light coming from fiber optics cables other than when we manually add it so we can work out what goes where.

[@Yorkie-UK]

Fibre optic isn't a wire, its fibre optic core, copper cable=wires or pairs of wires, fibre optic cable has cores. Also only multimode (local distribution typically in LANs) uses internal reflection. The main backbone of optical fibre is single mode which uses a Gaussian profile along the core. What your talking about is a new form of multiplexing to increase bandwidth.

[@teknophyle1]

Remember kids, If you have fiber optic internet at your house it does not use visible light. It’s infrared, and if you look into the fiber you won’t see anything while it’s damaging your eyes. Sounds like OAM is new, but they have had the ability to use multiple frequencies, or “colors” of light in fiber optics for decades. DWDM (dense wavelength division multiplexing) can be used on the large scale between cities, or under the ocean for insanely fast data rates. www.thefoa.org/tech/wavelength.htm

[@kwinvdv]

I assume that "twisted light" (orbital angular momentum) refers to polarized light? So they can control and detect the intensity and phase of light in two directions with a small chip?

[@feynstein1004]

Keep in mind that this won't increase internet speeds for a single user. Modern computers aren't able to fully utilize 1 Gbps ethernet because the data transfer speeds are on par with the read/write speed of the hard disk. Although, the RAM is much faster than the hard disk. So, if we could store all that data on the RAM, we would be able to fully utilize the blazing speeds. I just found a superuser article that says the RAM has speeds of 2-20 GB/s. That's right. Giga *bytes* per second, not *bits* . So I guess storage won't be a bottleneck for the internet, provided we utilize the RAM. If we want to download something, however, we'll have to store it in permanent memory, which will be much slower (SSDs have read/write speeds of 50-200 MB/s, hard disks are even slower).

[@shanepayback]

M.2 is lot faster my one R/W at 3,500MB/s to 2500MB/s and there's faster one's out there

[@feynstein1004]

@Shane McVay Ah right. I forgot about those. However, most people are still using HDDs because SSDs are so expensive. Perhaps in the future things will be different.

[@Taylor-vy2gg]

Can you guys make a video on submarine communications cables? Sounds interesting.

[@johnj8639]

Aren’t most wires still just copper? And as far as I know you can have a wide range of frequencies on both copper and fiber traveling at the same time without interference, (on top of that there are other tricks to add more bandwidth on the same line without interference too) I don’t understand if this will have much more of an advantage, other than possibly cheaper for having to bundle less cables.

[@lasarith2]

John J I once got 378Mbits/second for 2 hours ... which is far beyond the limit of 16Mbits/s they said my line (before fiber) could take - even I was 🤷🏼‍♂️ as to how it could happen .

[@ipissed]

You just diarrhea mouthed your ignorance.

[@johnj8639]

@ipissed Nice name. This was more or less the point. I was hoping someone could give me a clearer explanation. Clearly you can't.

[@johnj8639]

@lasarith2 yeah I have a copper line, and pretty much a constant 200mb/s. I assume it doesn't have as low latency as fiber, but to most servers where I'm from latency averages 10-20ms, and all of my testing has been over 5Ghz wifi.

Why not just refer to it as analog optics and digital optics? Current fibre is multiplexed digital signal. This is just frequency modulated optics. It's pretty much Morse code vs. FM radio.

While the technology for transmitting more data faster keeps improving in laboratories, the gap between those who can get even moderately fast Internet or any continues to widen. Because the access to Internet service is often monopolized in many areas, its left to the whims of the provider as to who they will connect. So, many parts of even well wired states, like Ohio, still can't get high speed Internet or have to settle for overtaxed and unreliable sources.
