Han Yi didn't go anywhere, just read quietly in the library of Jinshi University, even if there was a commotion in the Baolong shopping mall, he shouldn't know.

I came back at five o'clock in the afternoon, and spent all the time in the library except for dinner.

At eight o'clock, Han Yi, who was reading "Micro-Nano Photon Integration", felt that the afterglow was dim, and then he saw two Introduction to Electronic Communication on the table, and when he turned his head to look, he found that it was Song Yunxiang.

Only then did Han Yi remember the matter of asking her to help annotate, stood up and said embarrassedly: "I forgot to be busy with something these days." ”

Song Yunxiang stared at him for a while, making sure that he didn't look like a liar, before nodding.

Just wanted to leave, when he saw the photon integration theory on the table, he gave him a strange look, and couldn't help asking, "You... Why do you study photonic crystals?"

"I just want to use the optical path for control system and storage. Han Yi knew that the girl in front of him had a wide range of knowledge, and should be able to understand what he was talking about.

Sure enough, Song Yunxiang raised her delicate eyebrows, "This is very troublesome, if you want to achieve control, you need to perform some basic mathematical operations on the optical signal, including integration, differentiation, Hilbert transform, Fourier transform, and so on." There are also research sets that use optical fibers and fiber gratings to achieve these functions, and can theoretically be transplanted to chips, but there is no literature yet. ”

"I don't know much about optical storage, but I know that there are technologies that use the slow light effect in semiconductors, or the dynamic grating generated by Brillouin scattering to write and read light pulses, and so on. ”

Han Yi said: "You're right, I'm just thinking about shrinking the device, to the extent that it is like the current integrated circuit." It is a pity that silicon photonics technology is still blank in China. ”

The "silicon photonics" technology in Han Yi's mouth is a low-cost, high-speed optical communication technology based on silicon photonics, which uses laser beams instead of electronic signals to transmit data.

Song Yunxiang nodded and said: "There are indeed relatively few domestic studies on silicon photonics technology. The leading companies in this regard are Stanford and the University of California, and Intel should have relatively mature technology, but unfortunately it is still in a state of secrecy. ”

"Well, Intel ......"

The two of them just stood there talking, forgetting that this was the library, and before they knew it, their voices became louder.

Some people are not happy, the two of them opened their mouths for optical storage, closed their mouths for silicon photonics, and started to talk about Stanford Intel, making them look like experts and scholars, giving people a very pretending feeling.

"Hey, buddy, this is the library, if you want to pick up girls, can I trouble you to go out and go soaking?" said the boy who came over to Han Yi.

Han Yi was thick-skinned and didn't care, and Song Yunxiang, who had entered the Xueba mode, didn't even roll her eyelids, but when people put forward their opinions, the two of them were also very conscious, so they immediately changed to the corridor outside and continued to chat.

Song Yunxiang is worthy of being a talented woman, especially her opinions are very unique, every time Han Yi says a word, she can draw inferences from one example.

Just like the optical path control system, Han Yi has also read professional books for many days before he can get to the surface, but Song Yunxiang obviously doesn't know much, but he speaks in an orderly manner.

"For example, normally light travels in a straight line, but if it passes through a small hole, then there are two cases, if the hole is significantly larger than the wavelength, then I can see the image of the hole..."

Han Yi listened quietly, and waited for her to finish before asking, "Do you estimate that there will be any obstacles in tomography with photoconduction imaging?"

Song Yunxiang nodded and said, "There must be an obstacle." Light is a type of electromagnetic wave, and it has wave-particle duality, which is naturally affected by electromagnetic fields and gravity. ”

Han Yi didn't speak, and pondered there.

Again, it doesn't matter if you don't know why, but you at least need to know it.

Holograms are a century-old technology that encompasses countless disciplines, and you can't just take out a hologram with a tat and a thigh and publish it, and the consequences of that would be very serious.

Since holograms are not available for the time being, he plans to start with mixed reality technology as soon as possible, which is the ultimate version of CR that we are familiar with AR, and the effect is much more realistic than the whale video released by the American company magic Leap.

In this way, it will pave the way for the subsequent photoelectric conduction, human-computer interaction, and the shocking release of holograms.

At that time, what BAT, what Microsoft, Google, all die, Tianyi Technology dominates the world.

Thinking about it, Han Yi's heart became hot.

Seeing that he was in a daze there, still swallowing saliva, Song Yunxiang asked, "Can you tell me now what you are doing researching photon crystals?"

"Uh...... Well......"

I just covered up the past with a sloppy eye, but I didn't expect this talented girl to remember it!

Han Yi rolled his eyes and said, "Otherwise, you can help me write an academic report on augmented reality, and I'll show you something good after New Year's Day." ”

Song Yunxiang glanced at him suspiciously, "You can't lie to me to help you do things, right?"

"Hehe, how can I be, do I look like that kind of person?" Han Yi said with an innocent face.

Song Yunxiang thought about it for a while and asked, "Which side do you prefer?"

"Realistic. It is better to join the path of the future development of photonic crystals. Han Yi said with a little flattering smile.

He's having a headache with the report these days. Professor Cheng's vision is so high, ordinary academic reports can't get into his eyes at all. It just so happens that the talented girl is here, if he doesn't "use", is he still Boss Han?

"Okay, but if you lie to me......" Song Yunxiang thought for a while, but she couldn't think of any suitable words.

Then Han Yi laughed and said, "Lying to you is a puppy." ”

......

On the evening of December 30, the Zijinyuan Campus held a New Year's Day party in the auditorium, and all faculties sent elite soldiers to participate in the performance.

The opening group dance was performed by a female student from the Department of Economics.

The six girls in black vests and hot pants don't care about their appearance, but they have a bewitching posture and a graceful dance, and with a passionate song "Call Me Maybe", the audience exploded in an instant, and all kinds of wolf howls have not stopped since the music sounded.

Next is a handsome guy from the computer department, who gave full play to their expertise and designed a group of 3D animation beauties, as the music of "Fairy Tale" sounded, the handsome guy sang while interacting with the animated beauties on the big screen.

I forget how long I was holding steamed buns,

Squatting at the door of your house all night,

You have a dog in your house, and it's always barking,

Is it because I don't have bones......

When the crooked version of the lyrics sounded, the audience burst into laughter, and all kinds of whistles and flashing lights also came one after another.

At the end, a beautiful woman dressed almost like in the animation, with a rose in her mouth, walked out from behind the big screen, and the audience immediately applauded and cheered like a tide.

Next, the School of Power and the School of Engineering took turns to play, as the 506 dormitory is also the "grass" of electric automation, Luo Chun participated in it.

As the two handsome men and beautiful female hosts came off the stage, eight handsome guys wearing suits and ties and white shirts came up, and before the music started, many girls couldn't help but let out bursts of screams.

Jump back hat's that sound

Here she comes full blast and top don

Hot shoe burnin don the avenue......

As soon as the dynamic "Panama" came out, the girls on the scene stood up directly, screaming with their gloves on their mouths.

"Wow, so handsome~"

"Zhang Fanyu, I love you~"

"Peng Chengye, you are the best ......"

"Luo Chun......"

The eight people on the stage were obviously rehearsed in advance, dancing like each other, coupled with uniform costumes and handsome appearances, many girls on the scene were wet.

......

When Luo Chun and the others stepped down, Han Yi in the back court also left.

In 2017, I also turned over in all kinds of wolf howls, screams, and wet bodies......
