His wonderful universe

Is being continuously developing

The vast stars, the direction of "core"

"I want to know why such a small thing has the magic of achieving so many magical functions. I want to unlock the mystery."

During the Ph.D., Jin Ming chose a more practical direction in many directions -photoelectric chips, which is more interesting to make chips compared to most undergraduate students from surrounding most undergraduates.

The chip, when I was a kid, saw it at first glance, just like a black spot flashed in the starry sky, containing the secrets of the earth and the entire galaxy. When the black chip was in my hand, everything that could not be seen inside aroused my strong desire to explore.

Jin Ming said that the equipment used in the experiment is all giant and extremely expensive, but when a small chip is taken on the fingertips, it is seen from the light and shadow reflected from the mirror surface. The crystallization of wisdom. In Jin Ming's view, chip is very important for this era, which is also the original intention of his choice to engage in related research around the chip during his Ph.D..

During the blog, Jinming's research on chips involves all aspects from initial forms to application forms. He has developed a total of three types of light and electricity, facing three different system applications.

Optical sensing chip

The photoelectric sensing chip that Jinming initially studied at the beginning broke through the structure of the chip sensing. From the perspective of suppressing noise, he proposed a new sensing mechanism -1/f noise suppression of the dark field scattering, solving the solution to solve the solution The original photoelectric chip was the problem of low sensitivity when doing sensory. In the "New Crown Virus Test" national emergency resistance special specialty, combined with the sensor chip he proposed, the real -time tracking of the single virus in the air is only 1 yuan. The research results Jin Ming published on nature submun.

Chip used to signal transmitted layer

For the major strategic layout of the country's future "East West Calculation", Jin Ming integrates a large number of communication unit devices on a photoelectric chip, and cleverly "linkage" with micro -electrical chips to establish the highest density communication system Architecture. This is the second chip of Jinming research. This transmitting chip can also "collaborate" with parallel light source chips, realizing data transmission of Taobi. Related results, as an important part of the article, have been published in the Nature journal recently.

The chip used to receive signal

Corresponding to the second chip phase, the third chip of Jinming research can be used to receive signals. The chip not only becomes smaller, but the receiving rate of the unique channel on related signals can exceed 100 G Bit. Jin Ming used the new type of light field evolution mechanism to regulate the light and expand the system optoelectronic bandwidth. This chip is also combined with parallel light source chips, which can realize the transmission capacity of more than 2T -bit order, which provides a high -quality and low -cost solution for the next -generation chip dense wave score.

Whenever a small chip is completed, Jin Ming's heart will be encouraged:

As if a bunch of sand gathered together to give it magic power such as interconnection and communication. Create a small universe in my own hands, I think this is a very cool thing.

Pursuit of dark night, ideal light

"The scientific research process is very tempered, and the investment in it cannot be estimated. During this period, I was very lonely, but I must persist."

Behind all the achievements is Jin Ming's hard work and repeatedly trying to figure out countless times. He has to face the frustration and anxiety that has been broken again and again, but also to resist the loneliness that he has always adhered to in the darkness.

Jin Ming also clearly remembers that in the second grade of graduate students, facing the mentor's "soul question": "What are you have recently?" Successful: The surface of the chip was accidentally scraped by the sister -in -law to be re -made; this time the sample looks normal, except for the data ...

After a year of exploring the subject, I really wanted to give up without results. Fortunately, the instructor is always trying to help me solve it and encourage me. With the persistence after the frustration, the snowy night at four in the morning and the sunrise at six in the morning witnessed the compliance of the data, and I was finally received by the dissertation.

During the research process, Jin Ming's relatively large difficulty is to break through the performance limit of the sensor chip through the innovation of the physical mechanism. In physical mechanisms, the process is promoted simultaneously. This process has greatly exercised my exercise. "Jin Ming recalled," At that time, I had to make 4 groups of reports at that time, and there were constant new experimental data to promote discussions. "

During the experimental research stage, Jinming invested an average of 10 hours a day, and the data of a whole piece of computer hard disk was obtained before and after. Finally, three key experimental results were refined, which provided strong support for sensing chips and mechanisms. On the way to study optoelectronics, Jin Ming has gone for nearly 10 years. The laboratory, cafeteria, and dormitory of three o'clock lines also described his tenacity and attachment in the day and night reincarnation. He said "will continue on this road":

I hope to grasp the key technologies of chip manufacturing to our own own hands. I always feel that this matter must be done by someone. Why can't it be myself?

Pour blood and build my love

"Learn to accept the most authentic self, so as to avoid wasting energy due to struggle."

On June 16, at the graduation ceremony and degree awarding ceremony of the 2022 of the School of Electronics of Peking University, Jin Ming spoke as the first graduate representative of the Peking University Institute of Electronics. He mentioned a mark left by Peking University to himself is the free and true personality that Peking University atmosphere.

This free environment provided by Peking University allows us to discover the most authentic self, accept our ordinaryness, accept our confusion, and accept our choices. As a result, we can get the satisfaction and peace from the heart regardless of what we do, and we can grow freely and truly.

At the time of extra -curricular, Jin Ming was also keen to carry out related party group activities around the optoelectronic major, and all this was due to his hot and innocent love for the chip.

As the president of the Peking University Student Optoelectronics Information Association, Jin Ming likes to organize various rich and meaningful activities. "The starting point of my interested is that there are more excellent young researchers in the association, and there are many opportunities to communicate with the industry."

Jin Ming has repeatedly organized the Peking University Optoelectronics Association and the "House of Optical Fiber" of Shanghai Jiaotong University to conduct a dream linkage. In the past four years, he organized more than 100 students to visit the industry -related enterprises and institutions to conduct academic exchanges with relevant research institutions.

During the two years when Jin Ming served as the party branch of the School of Electronics, he often paid attention, feels, and thought with his classmates, and responded to the country's call for "building a strong country" with actual actions.

During the epidemic, Jin Ming organized the "everyone in the epidemic" online to share activities on the topic that everyone paid attention to, breaking through the way of learning in the past, and let everyone's heart cross the barriers of the epidemic.

Along the way, Jin Ming also has his own understanding and thinking:

No matter what you do, you must be willing to spend time. There is no shortcut to success. It is possible to focus on the innovation of research and the importance of cooperation with others. It is also important to manage emotions and adjust the mentality. I hope that students in the technology industry can communicate more with people around them and use the precious time in school to improve their ability to control their mentality.

Regarding the future, Jin Ming's thoughts are very simple. He hopes to continue to do something meaningful in chip research and development in a real and down -to -earth.
