Accessing Internet at 640 Gb/s - WOW !!

[naveen_reloaded]

University of Sydney physicists have developed an optical chip that could potentially improve ‘Internet speeds to up to 100 times faster than current Australia’s networks.’ According to the Sydney Morning Herald, these chalcogenide glass photonic chips will be very cheap to produce as they’re based on plain glass. As said the lead researcher, ‘we are talking about networks that are potentially up to 100 times faster without costing the consumer any more.’ He adds that these chips could be scaled to operate at data rates approaching 640 Gb/s — the equivalent to transmitting approximately 17 complete DVDs per second! These chips could be commercially available in 5 years with the possible first network deployments in Japan. But read more…

This research project has been led for 4 years by Professor Ben Eggleton, Director of the Centre for Ultrahigh bandwidth Devices for Optical Systems (CUDOS) at the University of Sydney. Please look at the research section about Photonic crystals for more details. Before going further, here is what this document says about chalcogenide glass photonic crystals. “Chalcogenide glasses combine a large optical nonlinearity with strong photosensitivity, making them ideal for studying nonlinear photonic effects. Chalcogenide glass photonic crystals are fabricated at the ANU by milling holes in chalcogenide glass films using a focused ion beam. We characterise these structures by measuring transmission and reflection versus incident angle and wavelength.”

Now, here is a quote from the Sydney Morning Herald article. “The device, a photonic integrated circuit, could overcome the gridlock that occurs when information travelling along optical fibres at the speed of light has to be processed by slow, old-fashioned electronic components. This would make almost instantaneous, error-free and unlimited access to the internet possible anywhere in the world, Professor Eggleton said. The market would ultimately decide which technologies were introduced to meet the skyrocketing demand for faster and cheaper downloads. ‘But our job at CUDOS is to go out to the absolute limit, and demonstrate in the lab what is possible,’ he said.”

In “Breaking the Internet’s glass ceiling,” a University of Sydney news release (July 9, 2008), you’ll find additional details. “‘This is a critical building block and a fundamental advance on what is already out there. We are talking about networks that are potentially up to 100 times faster without costing the consumer any more,’ says Federation Fellow Professor Ben Eggleton, Director of CUDOS, based within the School of Physics at the University of Sydney. Eggleton, whose team beat their deadline by a year, says that up until now information has been moving at a slow rate but optical fibres have a huge capacity to deliver more. ‘The scratched glass we’ve developed is actually a Photonic Integrated Circuit,’ he says.”

This research work has been presented at the 13th Opto-Electronics and Communications Conference (OECC) held in Sydney, on July 7-10, 2008, under the title “Error-free 640Gb/s demultiplexing using a chalcogenide planar waveguidechip” (PDF format, 3 pages, 268 KB).

The team also published a highly technical article for Optics and Photonics News, “Chalcogenide Glass Photonic Chips, Signal processing for the next generation of the Internet (PDF format, 6 pages, 484 KB). The picture above comes from this document.

Here is a key part of the conclusion of the paper. “Chalcogenide glasses offer an interesting and exciting new platform for developing all-optical signal processing devices for the photonic equivalent of the electronic chip. These devices will be able to demultiplex high data rate signals, convert the carrier wavelength, and perform other functions, such as optical signal regeneration and packet buffering and switching. Further improvements in device performance are needed in order to achieve all-optical signal processing at data rates for future telecommunications applications (e.g., at 160 to 640 Gb/s).”

Finally, if you want to learn more about these photonic crystals, take a look at an Elsevier scientific publication, Photonics and Nanostructures - Fundamentals and Applications and read the abstract of a paper called “Chalcogenide glass photonic crystals” (Volume 6, Issue 1, April 2008, Pages 3-11). “All-optical switching devices are based on a material possessing a nonlinear optical response, enabling light to control light, and are enjoying renewed interest. Photonic crystals are a promising platform for realizing compact all-optical switches operating at very low power and integrated on an optical integrated circuit. In this review, we show that by making photonic crystals from a highly nonlinear chalcogenide glass, we have the potential to integrate a variety of active devices into a photonic chip.” Interestingly, you cannot access the full paper for free from the abstract, but you can from the home page of the journal — at least today.

dream on!!!!

[Sumeet_naik]

I cud go wit 1 by 640 of tat speed..

[krates]

faster than my hdd speed

[amritpal2489]

!!!!!!!!! WoW !!!!!!!!

[Sukhdeep Singh]

I am happy even if i get 1Gb/s at nominal price of Rs 500 a month. No caps

[Lucky_star]

Now we need faster hard disks...

[max_demon]

we need content from net too*

[mavihs]

i'll be happy if i get even 50mbps!!!

[Cyrus_the_virus]

Guys, it for backbone networks, not for end to end connectivity, it's just going to increase the capacity of existing backbone networks so that it can support more users and remove existing throttling and not increase your end user speeds. It's just that instead of fibre optic cables, these cables could be used giving so much more bandwidth. So if you thought you already had a fibre optic connection to your house, then you can keep on dreaming about increased speeds.

[iinfi]

if at all it is going to increase my net speed i know wat MTNL's plan wud be

Speed:1 Gb/s, Amount:Rs.500, Duration: 1 month, Data Transfer: 1GB

[NucleusKore]

Now we need not worry about this

[max_demon]

we are not satisfied in what we get , suppose i now have 256 ul . i wish for atleast 2mbps speed . my oder friend has 2 mbps he wants 10 or 20 mbps . like that only . so even if we get that speed , we will desire for more

Economics student

[x3060]

just give me unlimited connection for 200/- , 1mbps ....thats enough

[ax3]

this speed in every1`s dreams .... or mayb its doom time ........

[ico]

Seriosuly, dream on!!!

Such types of things are invented every month or so, but the question which remains is..."When they'll go mainstream??".......

[ratedrsuperstar]

^or when will it go down the "indianstream"

[Ecko]

Now start pirating HD-DVD Rips

HaHa
We'll get 8MBPS BSNL at 2 Rs Unlimited
No newspaper
No TV
Just Internet

very true. Even d ADSL system(used by mtnl and bsnl) which uses the existing plain twisted pair copper wires can support upto 24Mbps per user. But that does not translate to 24Mbps download speed for us. In the end its upto the ISP how much bw it can afford to provide.

[jigu]

this shows how we indians are far behing in net speed.

don't be happy we have to wait for 10 yrs for this.

actually thats not always the case
im satisfied with my 256ul connection

[dheeraj_kumar]

I'll change my name* when BSNL introduces 2 mbps unlimited at <2000 rupees.
*conditions apply.

wow, that's a brave prediction. Did you know that India reached from 56Kbps to 8000Kbps in just 5-6 years? And the rest of the world reached from 0Kbps to 24,000Kbps in just under 20years? And at this rate, you still reckon it's going to take till 2070?

[Sukhdeep Singh]

Dont wory, When India progesses, it progress at a Rapid Pace. Take Mobile Phones as example, what was the scene ten years ago. Take our progress from Dialup to Broadband as a example even

correction are we getting 8000kbps for the same price as 56 kbps? Technology is there but what's affordable for most user matters here. Cellphones are common because its made affordable for everyone thats why we are using today. Now we should not tell 8mps connection is in India, bcoz its still not feasible for common people in India. So i Would say in 5-6 yrs the growth is only 5times, i.e 256 kbps.

^^ Do you remember the time when Internet hours pack used to costs in thousands ?

sorry dude, you got it wrong, even before broadband came, there were thousands of people like me who spent 300Rs for every 10hrs excluding phone charges and ended up paying about 3K every month for accessing the internet via dialup. Today, 8Mbps is already available in many places for 2K-3k and no time limits, you could probably get 10times more work done in a month than what you would do on a dialup. Sad to hear that you still think that 256Kbps is the norm.

He probably never used internet then or his parents never allowed him to spend that much money!

So what can u deny the fact that most Internet parlours at that time were running only 256/512 kbps? and home users were limited to 56kbps, thats the standard.
Now the growth in both extremes are 5 times..Internet centers upto 2mbps and for home users upto 256kbps...and am speaking uncapped and unlimited bb. Dont tell that we got 2mbps for 250RS.

I know dialup is costlier..but what about the broadband cost in 5 yrs dude? we were paying 900 4-5 yrs before for 256kbps and still we are paying amlost the same(reduced to 750 2 months before). 8mbps for 2k? intelligently used the keyword no time limits like what ISP normally reveal their plan, what about the download limit then? We aren't expecting 8mbps UL but atleast 2mbps unlimited for the price what we are paying now for 256kbps. IS the expectation so high?

He probably never used internet then or his parents never allowed him to spend that much money!

Nope I was using a corporate shared 56kbps account in 96-97, so only telephone rent counts.
