Twisted" fibre optic light breakthrough

Maybe this has been posted before but a team of researcher's has created a "new detector the width of a human hair" that can read twisted light.

A new development in fibre optics could make internet speeds up to 100 times faster – by detecting light that has been twisted into a spiral.

The research, published in the journal Nature Communications, can be used to easily upgrade existing networks and significantly boost efficiency, scientists say.

Fibre optic cables use pulses of light to transmit information, but currently information can only be stored through the colour of the light, and whether the wave is horizontal or vertical.

By twisting light into a spiral, engineers effectively create a third dimension for light to carry information: the level of orbital angular momentum, or spin. “It’s like DNA, if you look at the double helix spiral,” said Min Gu from RMIT University. “The more you can use angular momentum the more information you can carry.”

Researchers in the US had previously created a fibre that could twist light, but Gu’s team is the first to create a reasonable-size detector that can read the information it holds. 

Previous detectors were “the size of a dining table”, but the new detector is the width of a human hair. “We could produce the first chip that could detect this twisting and display it for mobile application,” Gu said.

would be nice if there wasn't any worry about data throttling from service providers

I WILL find your ITX build thread, and I WILL recommend the SIlverstone Sugo SG13B

Well we still have some kind of throttling but it's hardware throttling that does sometime happen during peak hours. But yes the provider at least don't throttle us up voluntary.

I mean neat but after 200megs you dont notice a difference at all. Also what is "internet speed". Fastest SFP you can get right now is 100gigs and 400 is right around the corner but that is all back bone.

This will be great for future content having full 4K TV/services streamed over fiber and 5G could be amazing, and also might help improve latency and servers response if data has to travel between less wires and switches and routers.

But it also means less cost for adopting this technology due to less wires required.

If the entire world adopts this tech (unless  very expensive) everything could become insanely fast and would enable other providers of videos, streaming  content hosting etc.

 

With SpaceX going for satellite contelation for internet globally, fiber 100 times faster(and possibly cheaper) 5G+ in the future, i would say internet should be declared a human right and maybe made free up to 10-20mpbs for people who are poor.

I would happily sacrifice 50mpbs of my speed so that other 2-3 households that cant afford can have access to internet. I know thats not how it works but thats what i would like to see by 2025 everywhere.

I am not sure where you are getting less wires from.

I've been to a Pint of Science event this spring and a researcher of University of Padua spoke about photon spin use for fiber optics, which his team has been studying for some years. However, the actual bandwidth increase would be about 8 times and would need larger fibers, but only one emitter (thus saving energy)

So photon spin research is not that new in this field

If people's internet speeds were actually tied to what is speed viable for the last mile on a large scale, we'd all have 10 gigabit like Chattanooga

muh specs 

Gaming and HTPC (reparations)- ASUS 1080, MSI X99A SLI Plus, 5820k- 4.5GHz @ 1.25v, asetek based 360mm AIO, RM 1000x, 16GB memory, 750D with front USB 2.0 replaced with 3.0  ports, 2 250GB 850 EVOs in Raid 0 (why not, only has games on it), some hard drives

Stuff- k70 with reds, steel series rival, g13, full desk covering mouse mat

All parts black

Workstation(desk)- 3770k, 970 reference, 16GB of some crucial memory, a motherboard of some kind I don't remember, Micomsoft SC-512N1-L/DVI, CM Storm Trooper (It's got a handle, can you handle that?), 240mm Asetek based AIO, Crucial M550 256GB (upgrade soon), some hard drives, disc drives, and hot swap bays

Screens- 3  ASUS VN248H-P IPS 1080p screens mounted on a stand, some old tv on the wall above it. 

Stuff- Epicgear defiant (solderless swappable switches), g600, moutned mic and other stuff. 

Laptop docking area- 2 1440p korean monitors mounted, one AHVA matte, one samsung PLS gloss (very annoying, yes). Trashy Razer blackwidow chroma...I mean like the J key doesn't click anymore. I got a model M i use on it to, but its time for a new keyboard. Some edgy Utechsmart mouse similar to g600. Hooked to laptop dock for both of my dell precision laptops. (not only docking area)

Shelf- i7-2600 non-k (has vt-d), 380t, some ASUS sandy itx board, intel quad nic. Currently hosts shared files, setting up as pfsense box in VM. Also acts as spare gaming PC with a 580 or whatever someone brings. Hooked into laptop dock area via usb switch

I guess he means less wires for equivalent current throughput.

Yeah but real world bandwidth usage is much smaller that people make it out to be. Cost of hardware is the cheap part.

No doubt about it but we have a leg of about 1000 100meg customers and it hovers around 2-4gbps at any one time. 

 

Just saying with backbones of 100gbps and upcoming 400gbps, no need right now for 40tbps

Pretty impressive stuff. Even Fibre Optics themselves are an impressive technology so the potential is huge.

So they are using circularly polarized light? I thought that was already a thing, It is in radio.

Ah the new routers will run on Spiral energy. Now every time the connection goes down, we can just believe in it and it will be up again in no time!
