I Am the President of the University

Chapter 480 Characteristics and Progress of Photonic Chips

On the podium.

Ren Hong looked calm.

All the cameras were facing him, and he was projected on the big screen behind him. Even if he didn't look back, he knew that his expression was displayed in front of thousands of people in the conference hall.

No, plus the major domestic and foreign channels that are broadcasting live, there are more than a million people watching his report.

He raised his head and briefly glanced at the people sitting in the venue, and a trace of sadness flashed in his eyes.

"Teacher, it would be great if you could see this scene."

Thirty years ago, when he left the mountains and rivers of his motherland, he took a ship for more than half a month and set foot on the beautiful country to start his study journey.

However, everything was not as beautiful as he imagined.

At that time, China had not yet taken off. As an international student from China, even the world-famous California Institute of Technology still faced discrimination.

His mentor, Professor Andres, is a German-American, over seventy years old, and a famous electronics scientist in the United States.

As an international student from China, Professor Andres was not only unbiased, but also often called him home for dinner because of his frail body.

On the other side of the ocean, at the home of Professor Andres, Ren Hong felt the warmth of home.

Meeting such a good teacher, Ren Hong worked hard and wanted to study 24 hours a day.

He still remembers what his teacher said to him.

"Ren, I see the shadow of Professor Qian (Xuesen) in you. You Chinese people are not only smart but also able to endure hardships. I believe it won't be long before China will rise."

When the teacher was young, he had taken a dynamics course from Mr. Qian. At that time, Mr. Qian was actually a professor at the California Institute of Technology and the director of the Jet Propulsion Center.

In the teacher's heart, he has always believed that Ren Hongfang will become the next Qian Xuesen.

So when the millennium came, he chose to accept the invitation from his alma mater, the University of Science and Technology of China, and prepared to return to China to contribute to the country.

After Professor Andres found out, instead of trying to dissuade him, he even gave him some important notes.

"Ren, I believe that one day in the future, you will become a famous electronics scientist in China! Old Andres will be proud of you even in heaven!"

However, five years after he returned to China, before Ren Hong became famous in the world, Professor Andres died of illness.

Ren Hong's eyes were particularly determined, on this podium and in this conference hall.

He's going to start his report.

Let Optical Core say hello to the world on behalf of China!

[Characteristics and Progress of Photonic Chips]

【Ren Hong】

【Professor of University of Science and Technology of China】

[Director of the State Key Laboratory of Integrated Circuits and Systems]

【December 2020】

This Ren Hong spoke in Chinese, but fortunately there was simultaneous interpretation through the headset, so everyone could understand what Ren Hong meant.

The reason why this China Forum has attracted hundreds of experts and scholars from abroad in the fields of semiconductors, materials, etc. is, of course, to wait for Ren Hong’s report on the topic of optical cores.

Almost all relevant scholars around the world are curious to what extent the Optical Core Research Center's research and development of optical cores has reached?

Is it a leap in progress or no achievement at all?

Once the optical core is successfully launched, it will not only change the mobile phone industry, but also subvert many other related fields.

Even with the success of photonic screens, many people are still not optimistic about optical cores.

Foreigners cannot understand the content of PPT and can only rely on listening. But some domestic scholars were stunned after looking at the content on the electronic screen.

"Hey, is Professor Ren still at the University of Science and Technology of China? I thought he had moved to Guanghua University..." Wei Hong rubbed his eyes, and when he took a closer look, this picture was still correct.

"I also thought Professor Ren was already a member of Guanghua..." Geng Haobo was also confused for a long time.

"Is there a difference?"

Professor Huang Weidong shook his head, looked at Ren Hong on the stage and chuckled: "I see that now, only Professor Ren still thinks that he is from the University of Science and Technology of China."

Professor Sun Wenchang, who was listening carefully on the side, also nodded in agreement.

The discussion in the audience did not attract Ren Hong's attention. At this moment, he had entered a state of selflessness.

His face was radiant, and the electronic screen behind him was constantly changing.

Normally, someone in the back rows of an academic forum like this would leave on the way.

Therefore, if you want to attend an academic forum or academic conference, sit in the front row if you want to raise your hand to ask a question, and sit in the back rows if you want to get away halfway.

But the scene of this keynote report was very quiet, and no one left.

There were only the rustling sounds of taking notes and Ren Hong's voice coming from the stereo.

“The frequency conversion matching window is roughly adjusted within the 100GHz range by controlling the chip substrate temperature, and fine control at the MHz level is achieved based on previous work on the photoinduced microcavity heating effect [Optics Express 28, 11144 (2020)]… …”

While listening, Professor Broad noticed the concentration on the face of an old friend next to him and couldn't help but chuckle.

"Oh, it seems that our Chairman Miller still agrees with Ren's report."

As soon as he finished speaking, Miller's originally focused expression suddenly changed into an indifferent expression, just like a face change in a Sichuan opera.

"Professor Broad, I didn't say that I agreed. Please pay attention to what you say!" Miller said lightly. .

Franz Miller, the chairman of this year's (International Solid-State Circuits Conference), is also a professor at UC Berkeley, an academician of the National Academy of Sciences of the United States, and a famous electronics scientist.

"Oh, God, is old Brod's eyesight?"

Professor Broad looked at Miller teasingly, "Professor Miller, do you still maintain your previous position on Guanghua University's optical core?"

Miller is the most influential figure in the field of chip design in the United States and even in the world, but the other party is not optimistic about China's optical core, and it can even be said to be opposed, and has made some radical remarks. speech.

After all, optical cores are still under research, so the outside world’s attitude towards optical cores is also polarized. One group believes that because of the emergence of photonic screens, many experts and scholars are very optimistic about the optical core research center of Guanghua University. Professor Broad, for example, is optimistic about Guanghua University; while the other group believes that China is lagging behind in the world in terms of chips. How is it possible? Will it overcome the world-class difficulty of optical core? Not only do they not believe it, but they also slander Guanghua University internationally, mainly Professor Miller.

"Professor Broad, science is rigorous and sacred!"

Miller's face remained stern, he snorted coldly, and said firmly: "It's too early to make a decision now, Professor Broad might as well listen for a while longer."

"OK OK, then let's continue listening." Professor Broad nodded with deep understanding, and then shrugged at Xia Ning on the other end.

He seemed to be saying to Xia Ning: Look, this old guy not only has a bad temper, but also has a bad mouth.

Right in the middle of the row behind Professor Broad.

Professor Huang Qiuting from ETH (ETH Zurich), a world-famous engineering school, feels more uncomfortable the more he sits here.

Was he wrong?

Thanks to the two classmates [TPCERP Style and Nature] and [Allure Just for Citric Acid] for their tips, thank you!

Today, my condition is as bad as ever. My whole body feels very uncomfortable, my eyes hurt, my head is still very dizzy, and most importantly, my heart has been beating wildly all day.

There is a feeling that I am going to die suddenly and collapse at any time.

My mental state is so bad and my face has been pale all day. I have to go to bed quickly. There is only one chapter left today. I'm really sorry...
