The researchers — who are based at Zhejiang University and Westlake University — used a 2.5D out-of-plane architecture that integrates graphene monolayers on a gold–silicon columnar metasurface. These structures effectively act as individual photodetection units that allow a wide field-of-view to be achieved, similar to the ommatidia in the compound eye of some animals. The team created a 16 × 16-pixel chip by connecting the detecting structures with a 180 nm node readout circuit using through-silicon via technology.
As well as wide-angle detection, the system showed high absorption between 300 nm and 1,600 nm wavelengths. Its sensitivity was particularly high at the 1,550 nm wavelength that is important for communications, exhibiting an absorption of nearly 100% and a detectivity of 109 Jones.

CMOS 中的广角复眼
这两名研究人员分别来自浙江大学和西湖大学,他们使用了一种 2.5D 平面外架构,将石墨烯单层集成在金硅柱状超表面上。这些结构有效地充当单独的光检测单元,可以实现宽视野,类似于某些动物复眼中的 ommatidia。该团队利用硅通孔技术将检测结构与 180 nm 节点读出电路连接起来,从而制造了一个 16 × 16 像素的芯片。
除了广角检测外,该系统还在 300 nm 至 1,600 nm 波长之间显示出高吸收率。它的灵敏度在对通信很重要的 1,550 nm 波长下特别高,表现出接近 100% 的吸收和 109 Jones 的探测率。
