摘要:

将纳米光子学与电子学相结合有望带来革命性的应用,从激光雷达(LiDAR)到全息显示。尽管硅光子学正日趋成熟,但在普遍使用的体硅CMOS工艺中实现有源纳米光子学仍具挑战。我们提出一种无晶圆厂(fabless)方法,通过协同设计后端金属层以实现光学功能,从而将有源纳米光子学嵌入体硅CMOS。利用65nm CMOS工艺,我们制造了等离子体液晶调制器,其开关速度比商业技术快100倍。这种零改动(zero-change)纳米光子学方法可为大规模生产的芯片配备光通信、传感和成像功能。将纳米光子学嵌入主导电子平台,使纳米制造民主化,催生从芯片级激光雷达到全息光场显示等技术。

英文摘要:

Integrating nanophotonics with electronics promises revolutionary applications, from LiDAR to holographic displays. Although silicon photonics is maturing, realizing active nanophotonics in the ubiquitous bulk CMOS processes remains challenging. We introduce a fabless approach to embed active nanophotonics in bulk CMOS by co-designing the back-end-of-line metal layers for optical functionality. Using a 65nm CMOS process, we create plasmonic liquid crystal modulators with switching speeds 100x faster than commercial technologies. This zero-change nanophotonics method could equip mass-produced chips with optical communications, sensing and imaging. Embedding nanophotonics in the dominant electronics platform democratizes nanofabrication, spawning technologies from chip-scale LiDAR to holographic light-field displays.
