I Am the President of the University

on the podium.

Ren Hong's face was calm.

All the cameras were facing him, and he was projected on the big screen behind him. Even though 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 live broadcast, there are more than one million people watching his report.

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

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

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

However, everything is not as good as he imagined.

At that time, Huaxia had not yet taken off. As an international student from Huaxia, even the world-famous California Institute of Technology was discriminated against.

His mentor, Professor Andres, is a German-American, over seventy years old, and a well-known electronics scientist in the beautiful country.

As an international student from China, Professor Andres not only has no prejudice, but also sees his frail figure and often calls him home for dinner.

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

Encountering such a good teacher, Ren Hong was so angry that he wanted to spend 24 hours a day on his studies.

He still remembers what the teacher said to him to this day.

"Ren, I see the shadow of Professor Qian (Xue Sen) in you. You Huaxia people are not only smart but also able to endure hardships. I believe that China will rise up soon."

When the teacher was young, he took Qian Lao's dynamics course. At that time, Qian Lao was really a professor and director of the Jet Propulsion Center at the California Institute of Technology.

In the teacher's heart, he always believed that Ren Hongf would become the next Qian Xuesen.

So when the millennium came, he chose to accept the invitation of 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 dissuading him, he also gave him several 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!"

only,

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

Ren Hong's eyes were particularly firm, in this podium, in this conference hall.

He is about to start his report.

Let Guangxin say hello to the world on behalf of Huaxia!

【Characteristics and progress of photonic chips】

【Ren Hong】

【Professor of University of Science and Technology of China】

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

【December 2020】

This Ren Hong speaks Chinese, but thanks to the simultaneous interpretation in the headset, he can understand Ren Hong's meaning.

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

Almost all relevant scholars around the world are curious about the research and development of optical cores by the Optical Core Research Center.

Is it a leap of progress, or nothing?

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 the photonic screen, there are still many people who are not optimistic about the optical core.

Foreigners can't understand the content of PPT, they can only rely on listening. But some domestic scholars were stunned when they looked at the content on the electronic screen.

"Hey, is Professor Ren still at the University of Science and Technology of China? I thought I had already moved to Guanghua University..." Wei Hong rubbed his eyes, and then he looked at the picture again.

"\\bI also thought that Professor Ren was already from 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 said with a light smile: "I see now, only Professor Ren still thinks he belongs to the University of Science and Technology of China."

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

A part of the discussion below the stage did not attract Ren Hong's attention. At this moment, he had entered a state of ecstasy.

The face is radiant, and the electronic screen behind it is constantly changing.

Normally, there will be people in the back row of an academic forum like this one who would run away on the way.

Therefore, if you want to participate in academic forums and academic conferences, you can sit in the front row if you want to raise your hand to ask questions, and sit in the back row if you want to walk away.

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

Only the rustling voice of taking notes and Ren Hong's voice from the stereo.

"By controlling the temperature of the chip substrate, the frequency conversion matching window is roughly adjusted in the range of 100 GHz, and based on the previous work on the heating effect of photoinduced microcavity [Optics Express 28, 11144 (2020)], the fine control of the MHz level has been achieved... …”

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

"Oh, it seems that our Chairman Miller still agrees with the report."

As soon as the words fell, Miller's originally concentrated expression was like a Sichuan Opera's face changed, and he instantly changed to an indifferent expression.

"Professor Broad, I didn't say I agree, 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.

\\b "Oh, God, is old Broad blinded?"

Professor Broad looked at Miller mockingly, "Professor Miller, do you still maintain your previous position on the optical core of Guanghua University?"

Miller is the most influential figure in the field of chip design in the beautiful country and even in the world, but the other party is not optimistic about Huaxia's optical core, and it can even be said that he is opposed to it, and made some radical comments. speech.

After all, the optical core is still under research, so the attitude of the outside world towards the optical core is also polarized. Because of the appearance of photonic screens, many experts and scholars are very optimistic about the optical core research center of Guanghua University. For example, Professor Broad belongs to Guanghua University. Will it break the world-class difficulty of the optical core? Not only unbelievers, but also slandering Guanghua University internationally, mainly Professor Miller.

"Professor Broad, science is rigorous and sacred!"

Miller's face was still stern, he snorted coldly, and said with a stubborn mouth: "It's too early to make a decision, Professor Broad might as well listen for a while."

"OK, then let's continue to listen." Professor Broad nodded in agreement, and then shrugged at Xia Ning on the other end.

It seems 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 the world famous school of science and technology ETH (\\bETH Zurich), the more he sits here, the more uncomfortable he feels.

Is he wrong?
