Recently, researchers from Zhejiang University, Westlake University, and the Institute of Microelectronics of the Chinese Academy of Sciences achieved a breakthrough. As reported in Advanced Photonics, they developed a 5-bit photonic memory capable of fast volatile modulation and proposed a solution for a nonvolatile photonic network supporting rapid training. This was made possible by integrating the low-loss PCM antimonite (Sb2S3) into a silicon photonic platform.
