According to a report by the American Physicist Organization Network on November 24th (Beijing time), scientists have achieved great success in using light beams to replace electrons to complete computing tasks in recent years. Now, researchers at the Massachusetts Institute of Technology (MIT) have filled a gap by being able to manufacture photonic chips based on standard silicon materials, which are the foundation of most electronic products today. In current communication systems, data is mostly carried by light beams and transmitted through optical fibers. Once the optical signal reaches its destination, it will be converted into electronic form, processed through electronic circuits, and then converted back into light using laser. The new device can eliminate these additional electronic conversion steps and directly process optical signals. The relevant research report was published in the online version of the journal Nature Photonics on November 13th. Professor Caroline Rose from the Department of Materials Science and Engineering at the university stated that this component is similar to an electronic diode. A diode allows current to flow in one direction and constrains it from flowing in other directions, forming a "one-way street" of light. In order to develop this device, researchers must find a material that is both transparent and magnetic, and these two properties are rarely achieved simultaneously. They eventually adopted a material called garnet. The researchers used methods such as garnet film deposition, and the entire system can be made based on existing standard microchips, greatly simplifying the manufacturing process. The new optical chip can significantly improve the speed of data transmission systems, as the transmission speed of light is faster than that of electrons, and optical computing can use multiple beams of light to carry different data streams and pass through a single fiber or circuit without obstacles. Rose stated that new systems based on silicon are easier to commercialize than systems based on other materials because many people know how to handle silicon, which may lay the foundation for developing the next generation of high-speed communication systems. Professor Bodani Steed from the Department of Electronic and Computer Engineering at the University of Minnesota also stated that this is a significant advancement in the field of fiber optic communication. This achievement is crucial as it involves integrating garnet into silicon devices. When humanity casts a longing glance towards the beautiful era of ultra high speed information processing, the graceful figure that appears ahead must be a photonic chip, and this fate is predetermined. And the familiar electronic chips that are currently accompanying us can only quietly leave. At present, the data transmission rate of photonic chips is 10Gb/s, which is several thousand times that of personal computers. The next generation of devices is expected to reach 40Gb/s, but we know that it cannot be practically applied yet. Compared to electronics, it is more difficult for photons to be arranged by us. However, this is also what the Ma Li team is working on in this article - using standard industrial chips to control and guide light as freely as they control electrical signals.
