Advances in Micro-Nano Optical Manufacturing

Dear Colleagues,

The field of micro-nano optical manufacturing has witnessed transformative progress in recent years, driven by the urgent need for subwavelength-scale optical components and systems across photonics, biomedical sensing, and quantum technology applications. Breakthroughs in nanoscale fabrication methodologies, ultra-precision metrology, and functional material engineering are enabling unprecedented control over light–matter interactions at micro-nano dimensions. This Special Issue highlights cutting-edge innovations in micro-nano optical manufacturing technologies, with a particular focus on bridging fundamental research to industrial-scale implementations. Key areas of interest include, but are not limited to, the following: advanced nanolithography techniques (e.g., multi-photon lithography, nanoimprint replication), functional micro-optics fabrication (including metasurfaces, photonic crystals, and hybrid plasmonic devices), precision characterization methods for sub-100 nm features, and system-level integration strategies for wafer-scale optical systems. Emerging topics such as quantum dot/nanorod manufacturing, AI-driven process optimization, and 3D-printed micro-optical arrays are particularly encouraged.

We believe that this collection of articles will serve as a valuable resource for those interested in micro-nano optical manufacturing and its applications. We hope that it will inspire further innovation and collaboration in the field, leading to new perspectives and breakthroughs in micro-nano optical manufacturing. It is within this context that we announce the Special Issue of Photonics on ‘Micro-Nano Optical Manufacturing’.

This Special Issue intends to provide a timely opportunity for scientists, researchers, as well as engineers to discuss and summarize the latest inspection methods in industrial applications. We invite papers that include, but are not exclusive to, the following topics: micro-nano manufacturing, optical component, nanoscale fabrication technologies, process-characterization co-design, optical design, image fusion, defect inspection, machine learning, metasurface manufacturing, ultra-precision machining, machine vision, functional optical materials, precision measurements and metrology, freeform design, manufacturing technology, opto-mechanical design, additive micro-optics, and advanced optical manufacturing and detection. Both theoretical and experimental studies are welcome, as are comprehensive reviews and survey papers.
