Currently, most of the optical signal input and output of co-packaged optics use edge couplers, and the use of V-slot can simultaneously reduce the alignment error and transmission loss requirements, so that the optical fiber to the silicon photonic crystal can be used for the transmission of optical signals to the optical fiber. ...

Although silicon photonics technology has been developed for more than 20 years, it is only in the last two years that the huge data transmission demand driven by the rise of generative AI has been explored and emphasized, so it and its derivatives have become the most important technology in the world. ...

In the past, since silicon photonics was mainly at the stage of technical research and development without extensive commercial applications, almost no domestic manufacturers except for a few academic institutions invested in research and development, which led to the development of a new technology for silicon photonics in China, which is now known as "silicon photonics" in China. ...

In addition to silicon photonics process technology, interface technology is also an important part of the process. Fig. 2 shows the development trend of communication interface for data centers, the earliest of which was the use of copper cables. ... Read more

Currently, silicon photonics technology is usually fabricated on SOI wafers containing a laser source that converts electrical signals into optical signals, a light sensor that converts optical signals into electrical signals, and an optical sensor that converts optical signals into electrical signals. ...
