In the past, since silicon photonics was mainly in the stage of technology research and development, without extensive commercial application, except for a few academic units, almost no domestic manufacturers invested in research and development, resulting in China's silicon photonics technology lagging far behind the United States and Europe. ...read more

In addition to silicon photonics process technology, interface technology is also an important part of the process. Figure 2 shows the development trend of communication interfaces for data centers. The earliest development was the use of copper cable connectors to connect telecommunication signals via the ...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, a modulator that increases the bandwidth of the optical signals, and a transmitter that increases the bandwidth of the optical signals. ...read more

With the rapid development of new technologies such as AI, IoT, and 5G driving the demand for huge amounts of data computation, in addition to the use of high-speed computing chips, inter-chip communication is another key factor to increase the speed of computation. However ...read more

The grown silicon carbide monocrystalline ingots are then subjected to a cutting process. Due to its hardness and brittle characteristics, the cutting of the ingots is difficult and prone to wear and tear, thus requiring high equipment stability. ...read more

The production of silicon carbide substrate needs to go through the process steps such as long crystal, cutting, edge grinding, grinding, polishing, cleaning, shipment inspection, etc. Among them, the key to affect the quality is the long crystal and cutting process. The earliest production of silicon substrate was in 1892. ...read more
