光纤水平低损耗硅晶圆光导制成 有助推动下一代光子集成电路发展
Ke Ji Ri Bao· 2026-02-09 00:55
相比当前广泛使用的氮化硅材料,新平台在近红外波段已具备相当性能,在可见光波段优势更为明显。 再通过低温退火工艺,波导表面可达到原子级平整,显著抑制散射损耗。在可见光波段,其性能较氮化 硅现有纪录提升约20倍。 尽管芯片尺寸仅约2厘米,但光在环形谐振腔等器件中的有效路径长度可达米至千米量级,此时低损耗 尤为关键。 将光纤优异的低损耗性能延伸到光子芯片上,一直是光电子领域的重要挑战。现在,美国加州理工学院 团队终于在可见光波段,成功制备出光纤水平的低损耗硅晶圆光导。这项进展将推动下一代高性能、高 相干性的光子集成电路的发展,未来可广泛应用于片上光学时钟、陀螺仪等精密测量系统,以及人工智 能数据中心通信和量子计算等领域。该成果发表于最新一期《自然》杂志。 目前,团队已利用该材料制备出环形谐振器、多种激光器及非线性频率生成器等。 团队开发出一种新方法,可将与光纤相同的锗硅酸盐玻璃以光刻工艺制备在硅晶圆上,在光子芯片低损 耗光导研究方面取得关键突破。他们使用8英寸或12英寸晶圆,制备出螺旋状锗硅酸盐玻璃波导。这种 结构能在有限面积内有效延长光路,同时材料便于与光纤和半导体激光器高效耦合,有助于降低数据中 心等设施的能耗 ...
