Rebirth: I carry a desktop computer inside me

On September 14, the China National Quality Inspection Bureau issued a notice requiring Sanxing to recall the Sanxing Note7 sold in China.

In less than half a month, there are already two explosions.

And I heard that the second piece is the UP master of a BI station.

Still a cold blow.

However, he was completely stunned, and the cold current that had always blown was said to have hurt him deeply this time.

It's been broken for the time being.

Subsequently, Civil Aviation of China also issued a message that it was forbidden to carry Sanxing Note7 on the plane or in check-in, making the attributes of Note7's flammable and explosive materials solid.

Sanxing knew that this machine king of Note7 was short-lived.

Some of Note7's memes are still being created on the Internet, but Jiang Cheng has not paid much attention to it.

This time, the Note7 did not burst the problem of memristor memory, perhaps, it can be left to the next generation of machine kings.

This pit is not difficult to find.

It's just that if there is no corresponding test, you can't feel it, you just feel that this technology is also very good.

After Jiang Cheng put this matter aside, he began to carry out research on optoelectronic chips.

In this research, Jiang Cheng has a very big advantage, that is, in the body supercomputing, it can simulate light.

It's like lithography.

In theory, light propagates information faster and farther than electricity, just like the optical fiber used for data propagation.

But compared with electronic chips, his shortcomings are also extremely obvious.

That is, the optical chip is not like an electric chip, the electronic chip through the transistor, very convenient to turn the electrical signal on and off, is this simple 1, 0, it is composed of kaleidoscopic analog and digital circuits.

But photonic chips are different, and there are no switches that can effectively control optical signals.

Jiang Cheng chose this direction, on the one hand, many large enterprises are already researching and layout, fighting is who has strong R & D strength, good luck, can find a faster way to solve.

The battery research and development center has been withdrawn, and Jiang Cheng directly transformed this place into a photoelectric chip research and development center.

As for talents, Jiang Chengcheng has a bit of a headache.

Nowadays, there are really no talents in Maple Fire to develop photonic chips.

Jiang Cheng himself can only be regarded as one.

After thinking about it, he still felt the need for cooperative research with universities.

It just so happens that Mizuki University and the Chinese Academy of Sciences have cooperated before, and this time the invitation is also very smooth.

"Dean Bai, what do you think of our research project?"

"It is a very cutting-edge research, and there are some research in our institute, especially silicon photonics chips, but this research is not so easy Oh, you have to be prepared to lose money." Bai Chunhua said very directly.

Jiang Chengtu said proudly, "Money is not a problem.

"It's also true, for us, it's too expensive to study this, and if you are willing to cooperate, I believe that the people in our institute who do this research will be happy to participate."

"That's good."

Bai Chunhua asked again, "Have you found cooperation with Mizuki University?" "

There will be a few graduate students over there, just to lay down and study together," Jiang Cheng pouted, "To be honest, what I want is a professor who knows more to participate."

"You want to invite Professor Luo Yu to study together, right?" Bai Chunhua asked with a smile.

Jiang Cheng smiled, "It's still Dean Bai who understands me." "

Professor Luo Yu has been studying high-speed optoelectronic devices for a long time, and he is a leader in China in this regard.

It is precisely the existence of these people that makes the research process of optoelectronic chips always be in the international leading stage.

Although there is no real product that can replace electronic chips, research has made great progress.

Bai Chunhua thought for a while and said, "After all, you haven't studied in this area, and he is naturally not happy to suddenly let him cooperate with you. "

You must know that Luo Yu has made a lot of achievements in this regard, such as DFB lasers, high-speed optical fiber communication, etc., why should people come to engage in scientific research cooperation with Jiangcheng's Maple Fire Group?"

Jiang Cheng nodded, "That's true, too." However, why is Dean Bai so supportive of me?

Bai Chunhua scolded with a smile, "I don't know you kid, the lithography machine can do it, and the photoelectric chip I think is not a big problem for you."

Jiang Cheng smiled, "Thank you Dean Bai for taking it seriously, but I don't know which professor of the Chinese Academy of Sciences is interested in coming?"

"There is a professor, Professor Zheng Wanning, who will lead the team to cooperate with you, of course, provided that your scientific research projects can impress her." Bai Chunhua said solemnly.

Jiang Cheng nodded, "Is she?" I've read some of the books she's written, and is she doing this aspect of photonic crystal laser research now?

"Well, you still have research in this field." Bai Chunhua said approvingly.

"Okay, taught myself for a while." Jiang Cheng smiled slightly.

"She should have time at the end of the year, so do your research first and see if you can come up with a project topic that interests her." Bai Chunhua said with a smile.

"Good." Jiang Cheng answered.

The two hung up.

Jiang Cheng also thought carefully, he has been self-learning and research in this field, and now although he is not very proficient in a certain place, his extensive knowledge of cutting-edge technology, coupled with his own supercomputing help, has given him a higher understanding of the theoretical design of optoelectronic chips.

Just relying on switches to define photonic chips is definitely too straightforward.

Electronic chips, which can use transistors to control switches, represent the meaning of 1 and 0, but photonic chips are not the same, completely according to the logic of electronic chips, which is problematic.

It's also too hard to achieve.

Because the wavelength of the light wave is there, if the process goes deeper below 7nm, this wavelength is easy to go wrong.

Maybe it would be better to give the photonic chip a whole logic.

However, this problem is more difficult, which is equivalent to having to start all over again on the original binary based framework.

After setting up the R&D center first, Jiang Cheng arranged for the human resources department to recruit talents in several major universities.

Huagong, Mizuki, Kyoto, and Magic Capital Jiaotong University are all schools with strong optoelectronic majors, and Jiang Cheng wants to recruit people mainly from these schools.

While Jiang Cheng was guiding the research and development process of EUV lithography machine and preparing to build an optoelectronic chip research and development center, the 86th and 87th meetings of 3GPP were held successively.

What surprised Warwick was that Lian Xiang and Motorcycle actually had a big change in attitude, and all agreed with Warwick's plan.

It makes Warwick's Ren Fei feel a little incredible.

He also personally called Liu Wannian to thank him.

This time, although there is the support of Fenghuo, Lianxiang and other companies, due to the strong opposition of the Paste Camp, but the strong support of the Hua camp, in the data channel short code, the LDPC+Polar code method is chosen, and the control channel short code, only Polar code.

Polar code is Warwick's main technology.

That is to say, this time Jiang Cheng changed the result more or less by helping him.
