Special Issue Information
Dear Colleagues,
Recent advancements in optical nanostructures, metasurfaces, and photonic devices are opening new frontiers in a wide range of applications, including high-efficiency photovoltaics, optical communications, quantum technologies, biophotonics, and sensing. These innovations are reshaping how light is manipulated at the nanoscale, enabling precise control over wave propagation, polarization, and spectral characteristics. However, significant challenges remain in realizing the full potential of these technologies. For metasurfaces and optical nanostructures, one of the primary barriers is the inherent material losses in plasmonic components, which limit their performance in many practical applications. Additionally, there is a need for materials with specific optical properties, such as ultra-high refractive indices, strong anisotropy, and rapid, reversible responses to external stimuli. The absence of such materials impedes the development of metasurfaces that can operate efficiently across a broad range of wavelengths and conditions. Moreover, fabricating photonic devices and nanostructures with high reproducibility and cost-efficiency remains a significant challenge. To address these issues, the discovery of new materials, such as low-loss plasmonics, high-index dielectrics, two-dimensional materials, and those with tunable optical properties, is paving the way for next-generation metasurfaces.
The present Special Issue of Nanomaterials aims to present the current state of the art in the use of advanced fabrication techniques, novel material platforms, and innovative design principles to enhance the functionality of optical metasurfaces and plasmonic devices, with a focus on their integration into next-generation technologies. Novel materials offer the possibility of creating photonic devices that integrate seamlessly with existing technologies, such as complementary metal–oxide–semiconductor (CMOS) circuits, and support applications requiring extreme precision, tunability, and high performance. The integration of these materials into the design of optical nanostructures and metasurfaces is set to revolutionize fields such as integrated photonics, quantum information systems, and advanced sensing technologies. By overcoming current limitations, these developments are expected to enable more efficient, multifunctional, and scalable photonic devices that will play a pivotal role in advancing science and technology across multiple domains.
