- Professor in Department of Mechanical and Automation Engineering at The Chinese University of Hong Kong
- Research in recent years focuses on the development of ultrafast laser-based microfabrication and micro-additive manufacturing processes
- SRFS project — aims to address the major challenges in high-resolution photopolymerization processes, including resolution, throughput, cost, and reproducibility through two-photon lithography (TPL); and to enable large-scale applications of TPL and new functions such as optical part repair and modification for the first time. This project will develop a high-speed closed-loop projection-based TPL platform through the development of an optical diffraction tomography module to monitor the fabrication process in situ. Based on the new capabilities, this project will design, fabricate, and characterize large-scale optical and mechanical metamaterial structures and photonic devices with sub-50 nm resolution, generating significant impact in the nanomanufacturing and nanotechnology industry.

讚詞
陳世祈是香港中文大學機械與自動化工程學系教授,專注於精密工程研究。本研究旨在解決納米級3D列印(又稱雙光子光刻技術,TPL)領域長期存在的挑戰,並首次實現TPL的大規模應用和新功能,包括光學部件的修復和改造。
TPL是一種重要的增材製造方法,其特徵尺寸約為150納米。然而,最先進的商用TPL系統一直受到速度緩慢的困擾,局限於學術研究。為了實現TPL的實際應用,必須開發能夠同時提高解析度、速率和良率的新方法。
本計畫將開發一個基於高速閉環投影的TPL平臺,該平臺將透過開發光學衍射層析成像(ODT)模組來即時監測製造過程。快速的ODT系統將實現逐脈衝折射率監測及精確的雷射劑量控制。為了進一步提高分辨率,這項計畫將投影TPL與周邊光抑制的概念相結合,透過將投影雷射焦點與光抑制圖案疊加,可產生多達10,000個雷射焦點(分辨率為50納米),從而實現高速超分辨TPL。基於這些新功能,這項計畫將設計、製造和表徵分辨率低於50納米的大規模光學和機械超材料結構及光子裝置。
新的TPL平臺將對納米製造和納米技術產業產生重大影響。此外,ODT模組可以在不同的光聚合過程和無標記3D生物成像中找到更廣泛的應用。
