Chen Jianjun, a researcher at the Institute of Modern Optics at Peking University, told a reporter from Science and Technology Daily that so far, the development of microchips for terahertz processing has faced two major challenges: The chips are hot and difficult to expand. But physicist Uriel Levi of the Hebrew University of Jerusalem Dr. and his team showed the proof of concept of the new optical device preparation technology. This new technology combines the fast processing speed of optical communication and the reliability and expandability of electronic equipment manufacturing, and is expected to solve the above two major 'roadblockers'.
Optical communication encompasses all technologies that use light as an information carrier and transmit it over fiber-optic cable, such as the Internet, telephones, cloud, and data centers. Optical communication is very fast, but in microchips, optical communication becomes unreliable and difficult to replicate in large numbers .
In the latest research, Levi's team used the metal oxide silicon oxynitride (MONOS) structure to design a new type of integrated photonic circuit using flash technology on a microchip. If successful, it will make the current standard 8-16 GHz computer The speed of operation is increased by a factor of 100, and microchips with terahertz operating frequencies are made possible.
Levy stressed: 'The new research will help scientists develop new, more powerful wireless devices that will dramatically increase the speed of data transmission. This is a technology that changes the rules of the game. Now, we may be able to use high-precision and low-cost flash memory. Technology manufactures any optical device.
Chen Jianjun said: “High-precision and repeatable preparation of ultra-small photonic devices is an important guarantee for the realization of integrated photonic chips. New technologies bypass the current micronano-processing precision of photonic devices, and the problem of poor repeatability, the introduction of flash memory technology into silicon-based photonics In the processing of devices, reliable and repeatable photonic device fabrication is realized, which is of great significance for the realization of integrated photonic chips in the future.
