The non-destructive "optical pathway" is a complex large-scale project, more complex than AR, but once it is completed, it will be a matter of merit and benefit the future.

It's like replacing the current optical fiber with a silicon crystal lossless optical path, as long as your hardware device can support it, the speed of downloading a 10G small movie will definitely exceed that of the fastest movie.

However, thousands of high-rise buildings are rising from the ground, and they haven't even taken the first step yet.

Han Yi drove around to the faculty building at the north gate, Song Yunxiang was standing quietly under the ginkgo tree and waiting, the west sun poured on her, and the whole person was bathed in a layer of golden light, looking so dusty.

At this moment, a royal blue Volvo quietly slid to her side, the right window was lowered, and Han Yi, who was sitting in the driver's seat, shouted: "Get in the car." ”

Song Yunxiang stood still and asked, "Where are you going?"

"Go get the materials. ”

Song Yunxiang hesitated for a moment and got into the car, fastened her seat belt and sat there without speaking.

The car started slowly, and drove out of the gate towards the Tianyi Club.

On the way, Han Yi teased: "Just now, from a distance, you look like a feather ascending immortal, so beautiful." ”

Song Yunxiang said casually: "Actually, I'm not good-looking, but others don't think so." ”

"I've never seen anything like this...... Confident people. Han Yi was speechless.

Song Yunxiang had a hint of a smile in her eyes, and turned her head to look out of the car.

Now is the rush hour after work, the traffic is busy, the car horns are honking one after another, and the traffic light is in front, Han Yi stepped on the brakes and said: "By the way, why do you have to take a long time, even ten days and half a month to reply every time I send a message?"

"Because I rarely use chat tools. ”

"Why?"

"Because...... There are often irrelevant questions thrown around. ”

Han Yi broke the casserole and asked, "For example?"

"For example, hello, what are you doing here? ”

Han Yi smiled awkwardly because he liked to ask "if he wasn't there" before every message.

"Then you can just answer it. ”

The light was green, the car moved forward, and Song Yunxiang said seriously: "How do you want me to answer?"

I said yes and asked me what if I borrowed money? I said no, what if I was invited to dinner? So if there was something to do, I would just say it so that I could know if I was there or not. ”

Han Yi didn't hold back for a while, and laughed.

The longer you have been in contact with Song Yunxiang, the more you will find that she is actually a very humorous person, provided that you don't think about it, or you may be hit by tons.

......

Tianyi Experimental Building.

After Song Yunxiang got out of the car, she looked around and asked curiously, "Where is this?"

"Tianyi Experimental Base. Han Yi locked the car door and said.

Looking at the two buildings hidden among the lush trees, Song Yunxiang had a hint of surprise in her eyes and asked, "Yours?"

"Yes! ”

Han Yi had a look of pride on his face. Half of his assets for more than half a year were spent in these two experimental buildings, and he dare not say that the equipment in them is the top in the world, but it is definitely second to none in China.

The two of them walked towards the building, and on the way, Han Yi personally explained, "Building 1 is the main building of AR experiments, and Building 2 is material stripping. ”

Song Yunxiang asked: "What is the use of the secondary stripping of silicon photonics crystals?"

Han Yi glanced at her and said with a smile: "You also know that the silicon crystal is stripped twice?"

Song Yunxiang glanced at him and didn't speak.

Han Yi touched his nose and explained: "Augmented reality consumes a lot of power, especially for playing games, and the 2000 mAh battery can support about 30 minutes, which is obviously not suitable for mobile devices, so I plan to use photovoltaic sun on the bottom panel of the mobile phone." At present, the main problem is that the bonding strength of silicon crystal EVA and TPT backplane is not enough, and multi-layer peeling experiments are required. ”

After he finished explaining, Song Yunxiang was shocked in her heart and asked, "How can you be sure that silicon crystal EVA will definitely be better than EVA?"

EVA is a rubber foam made of ethylene, which is often used as an adhesive layer in the middle of solar panels.

The reason why Song Yunxiang asked this is because every process of mainstream solar panels has gone through thousands of tests before making a finished product, and it is no problem to say that it cannot be changed. Now that Han Yi is directly stripping the silicon photonic crystal, does it mean that there is already a finished product? Or does he know the final result?

"The scientists told me. Han Yi said vaguely.

"Can you let me meet him, I want to ask him a few questions?" Song Yunxiang asked expectantly.

"Oh, I'll ask him when I get back, but there's not much hope. ”

"Why?" Song Yunxiang asked after breaking the casserole.

"He has an eccentric personality and easily does not see outsiders. ”

Just in front of the silicon crystal material room, Han Yi stepped forward to check his fingerprints, enter the password, and with a "click", the double-layer telescopic security door shrank into the wall.

The room seems to be designed with dust-free and low temperatures, and there is still cold air coming out at the moment when the security door is opened. Looking at the room again, about 20 square meters, there are several rows of stainless steel shelves against the wall, each row of five layers, each layer of five grids, and a 20×20 black box in the grid.

Han Yi walked to the shelf and checked his fingerprints, and the box opened with a "click", and inside were pieces of multi-layer silicon crystal experimental materials imported from the United States.

The price of this box of multi-layer silicon wafers is as high as 120,000 US dollars, and you must buy a complete set of experimental equipment from others, and do not sell it separately.

"How many slices?"

Hearing Han Yi's words, Song Yunxiang thought of an important thing, the experimental silicon wafer is expensive, isn't it good to take it away like this?

"How much does it cost?"

Han Yi pushed the boat along the water and said: "Otherwise, you will do experiments here in the future, and these silicon wafers will be regarded as my sponsorship of you." ”

Song Yunxiang glanced at him and said, "Are you tricking me?"

Han Yi smiled awkwardly and said, "You think too much, am I that kind of person?"

"Yes!"

Seeing Song Yunxiang's wary look, Han Yi said with three points of bewilderment: "The facilities here are complete, the scientific research personnel are also first-class in China, and there is also the opportunity to get in touch with the most cutting-edge technology in the world;

Although her heart was moved, Song Yunxiang didn't want to be persuaded by him so easily, and said, "I'll go to the University of Science and Technology." ”

Han Yi said proudly: "We are a joint laboratory with the University of Science and Technology, and Professor Zheng Peisheng is almost my mentor." ”

Without waiting for Song Yunxiang to continue, Han Yi put on gloves and took out four or five pieces of experimental silicon crystals, and said, "Let's go, or the alarm should go off." ”

When I came to the silicon crystal laboratory on the fourth floor, looking at the professional experimental equipment inside, many of them were specially customized, Song Yunxiang couldn't take a step at once, and never mentioned the University of Science and Technology again.

Han Yi taught her how to operate various equipment.

Song Yunxiang is really a good student, something goes over and over again, you don't need to say it a second time. When it came to the experimental link, it was as if he had opened a hanging, and he was extremely skilled, as far as Han Yi, who had been in the laboratory for more than half a month, was new and tender compared to her.

After doing two sets of experiments, Han Yi said, "It's not too early, let's come back tomorrow." ”

Song Yunxiang, who was standing in front of the test bench in a white coat and frowning and contemplative, did not look back and said, "You go back first." ”

"I'll go back first. You haven't done the identity verification yet, and the security guard will have to take you to the police station. ”

Seeing that Song Yunxiang was still hesitating, Han Yi said: "Let's go! Rome was not built in a day, and it is not too late to come back tomorrow." ”

Song Yunxiang reluctantly left the experimental building with him.

......

Early the next morning, Han Yi went to the real estate trading center to go through the transfer procedures, and in the afternoon, he took the time to help Song Yunxiang do an identity certification, and asked her to sign a so-called "confidentiality agreement".

Song Yunxiang always felt that something was wrong, but there was nothing wrong with the agreement, and she didn't plan to divulge any secrets, so she signed it after thinking about it.

After signing the agreement, Han Yi took the agreement and walked away with a wry smile, leaving Song Yunxiang to wonder in the laboratory for a while, and then left it behind and buried his head in the experiment.

Of course, there is nothing wrong with the agreement, but signing a confidentiality agreement is tantamount to acquiescing that she will stay in Tianyi Lab. didn't spend a penny, and "fooled" a talented woman with a superior IQ to work, can Han Yi not be happy?

Song Yunxiang, who had been guarding the embankment, would never have thought that she would be tricked in the end.
