Special Issue Information

Dear Colleagues,

Nanophotonics explores the rich interactions between light and matter at the nanoscale, revealing unique optical properties beyond conventional limitations. This Special Issue entitled “Advances in Nanophotonics: Physics, Materials, and Applications” of Micromachines welcomes cutting-edge research in plasmonics, metamaterials, nanophotonic structures, self-assembly techniques, spectroscopy, and related interdisciplinary areas. We seek contributions that illuminate both fundamental physical insights and innovative applications across diverse fields including, but not limited to, sensing, imaging, quantum information processing, energy harvesting, and biomedical technologies. By bridging theoretical advances with experimental breakthroughs, this Special Issue aims to catalyze new directions in nanophotonic research and technological development. We invite original research papers, short communications, perspectives, and review articles that advance our collective understanding of this intellectually stimulating and rapidly evolving field.

Meta-optics, enabled by metasurfaces consisting of two-dimensional arrays of meta-atoms, offers ultrathin and multi-functional control over the vectorial wavefront of light at subwavelength scales. The unprecedented optical element technology is a promising candidate to overcome key limitations in augmented reality (AR) and virtual reality (VR) near-eye displays particularly in achieving compact, eyeglass-type form factors with a wide field-of-view, a large eyebox, high resolution, high brightness, and reduced optical aberrations, at the same time. This review highlights key performance bottlenecks of AR/VR displays in the perspective of optical design, with an emphasis on their practical significance for advancing current technologies. We then examine how meta-optical elements are applied to VR and AR systems by introducing and analyzing the major milestone studies. In case of AR systems, particularly, two different categories, free-space and waveguide-based architectures, are introduced. For each category, we summarize studies using metasurfaces as lenses, combiners, or waveguide couplers. While meta-optics enables unprecedented miniaturization and functionality, it also faces several remaining challenges. The authors suggest potential technological directions to address such issues. By surveying recent progress and design strategies, this review provides a comprehensive perspective on the role of meta-optics in advancing the optical engineering of next-generation AR/VR near-eye displays.
