Νew Technologies and Innovation Development in Russia

The device, which is a disk with a diameter of 250 nanometers, is able to switch the optical pulses in the time, numbering in femtoseconds (a femtosecond is a millionth of a billionth of a fraction of a second)

Researchers from the Moscow State University Lomonosov as part of an international group established ultrafast photonic switch that works on silicon nanostructures. This device can be the basis of future computers and allow data transfer at a tremendous speed. Development of scientists presented in an article in the journal Nano Letters.

This development refers to the photonics - a discipline that emerged in the sixties of the last century, simultaneously with the appearance of lasers. The basic idea of ​​photonics - to do the same, making the electronics, but with the replacement of electrons by photons of light - photons. Their main advantage is that they hardly interact with each other and with the environment in which the subject, and therefore more preferable to transmit information than electrons. This can primarily be used in computers, which is the main indicator of performance. But at that time, as the basis of modern electronic devices - transistors - have characteristic dimensions of less than one hundred nanometers, the size of the prototype optical transistors were on the scale of a few micrometers. The structures also capable in this sense compete with electronics, such as plasmon nanoparticles are characterized by low efficiency and high losses. So the situation for a compact photonic scheme is deadlock.

But three years ago, researchers at a time of several research groups stumbled on an important effect: in nanoparticles of silicon were found strong resonance in the visible region of the spectrum, the so-called magnetic dipole resonances. This response is characterized by a strong localization of light waves in the subwavelength scale inside the nanoparticles. Effect interested many researchers, however, according to Maxim Shcherbakov, first author of the article in Nano Letters, no reason not to think that this discovery can form the basis of a compact and very fast photonic switch.

Nanoparticles are able to make the Australian National University by electron-beam lithography followed by plasma etching. This was done by graduate student Alexander Shorohova that took place there in the framework of an internship scholarship of the President of the Russian Federation. These samples were sent to Moscow, and all subsequent experiments were performed with them at the Physics Department of Moscow State University in the laboratory of nano-optics and metamaterials.

"In our experimental studies we have with my colleague Pauline Vabishchevich, an employee of the Physics Department of Moscow State University, used a large set of different nonlinear optical techniques associated with the interaction of femtosecond laser pulses with matter - said Maxim Shcherbakov. - We used femtosecond laser system, purchased under the program of development of the Moscow State University.

Ultimately, the researchers had received the device, which is a disk with a diameter of 250 nanometers that can switch between optical pulses during numbering in femtoseconds (a femtosecond is a millionth of a billionth of a fraction of a second). This allows the operating time in the future to create a device information transmission and processing speeds in the tens and hundreds of terabits per second. This speed would allow download thousands of feature films of high quality in one second.

Jobs created by the scientists of Moscow State University photonic switch is reduced to sending him two laser pulses, which, thanks to the presence in the silicon nanoparticles of magnetic resonance, very well communicate with each other. If the pulses arrive simultaneously, one them, managing, interacts with the second and quenches it due to the effect of two-photon absorption. If the pulses come with a gap in time just a hundred femtoseconds, the interaction does not occur, and the second pulse passes through the nanostructure has not changed.

"We managed to develop a framework, which also reduced to" no "to the role of free media, - said Maxim Shcherbakov. - Free media - that is, electrons and holes - in integrated photonics devices traditionally impose severe restrictions on speed signal conversion. Our work represents an important step for the development of active photonic devices - gates, transistors, and so on. N. Features of technology applied by us in our development, now allow to use it in the integrated circuits of silicon photonics. In the short term, we intend to verify these nanoparticles in the integrated performance. "

Will be more interesting if we actually get the news of it supposedly to be sold to China.

Problem is, Russia creates a lot of cool looking items but many of them don't get sold.  I have a feeling this one will end up the same.  People want more practical rather than batman looking (much like that Kamaz vehicle or whatever it was that people call the batmobile.  God, I hate batman and anything batman related).  They need to make more practical.  Wider seats, more seats, comfortable seats, etc.  People are getting fatter.  Need bigger seats.

A Hong Kong investor is to buy out 64.9% of shares in Yota Devices

Seems that Rostec still holds enough shares so they can block certain things, but essentially, the Chinese investment company now owns majority of shares in Yota Devices which makes the Yota Phone.  Not really Russian anymore.  I guess there are the other Russian phone tech companies whom to still throw weight behind.  Guess Rostec made a lot of money and decided to cancel holding majority shares in it.  I wonder if this deal will hamper Yota Devices from opening up the plant in Russia to build the secure smartphones (now being mostly owned by a Chinese company, I wouldn't trust it to be secured).  Dunno what to think over this.  Rostec so far has shown great results and has turned many companies around (UOMZ/Schwab) and profited enough hence why they are 10 ten largest companies in world.  But I feel this deal is really just a method for Rostec to make easy money by selling not only majority shares but to also make easy money since this company in China will really push Yotaphone sales in China which will mean easy dividends for Rostec.

Edit: Now that Yota Devices isn't really Russian anymore (about as Russian as Motorola is American), what other smartphone brands exist in Russia?  Neither companies as well make the smartphone in Russia like Yota.  But are now considered more Russian for sure.
So far, I found:
- TeXet

Any other brands?

T-Platforms is apparently interested in the mobile market, hence their participation in semiconductor industry through its subsidiary Baikal electronics. So they may be Russias ticket.  Currently, this deal for Yota devices, is gonna be a wait and see of the outcome.  But the relative poor sales gives me the indication that the expensive Smartphone market isnt for Russia.

Since Ruble is cheaper than Renmimbi and almost little tarrifs between Russia and China, if I had the money, I would set up a smartphone assembly plant in Russia. Subcontract out the manufacturing of the PCB to Kraftway using the basic of Chinese parts.  I imagine cost would be little and as long as I am not expecting 200% or more profit, I can make a pretty kopek.

sepheronx wrote:That was the problem. I seen them for as high as $800 CAD.  No way I am paying that. I feel burned over $250 CAD for my LG phone.

Russian industries need to have an objective. They need a plan.  The government will clearly have to step in like Vann said cause you cant trust private.  So what can be done? I suppose try to push the current tech developers in Russia to produce phones from their own products.  To produce other goods.  Russia has the industrial base, the tech, the knowhow, but the lack of willpower from people.

Maybe set tarrifs for such stuff so it is no longer profitable to import it.

According to the Russian version of Rostec (for whichever reason gives more details) states that Rostec still holds 26.1% of shares and the head honcho has 10% shares.  The Chinese company is just a pure investment company. Yes they own majority shares, but Rostec still has enough shares for vetoing and as well, has options to buy back shares (that was the agreement at least).  I have a feeling that it wasnt going anywhere in major sales as Yotaphone 2 didnt sell as projected either. So this may have been the last chance Yotadevices would have been able to churn out a profit.  It didnt even sell well in Russia. Brands like texet seems far more popular (somewhere on this site had info on Russian brand phones selling well recently and which brands. Cant find it atm). But Yotaphone was expensive and already made outside the country.  Current guy is still general director of Yota devices so plans may stay the same or not. It is a wait and see.

Texet on the other hand seems to offer cheap cell phones and sells lots of them. Of course, their phones are also chinese made.

Rostec is a state own corporation (one of the 10 largest in the world) and they have done wonders for various companies. But I have a suspicious feeling that this was a last attempt to get something out of their investments and a big chance to make money from Yota Phone.  The 26.1% shares will guarantee profits one way or another and as well some general say in development.  May keep Russian engineers employed as well.  Much like when Motorola was sold to a Chinese company.
