Special Issue Information

Dear Colleagues,

Nanoscale photonics is an interdisciplinary subject that combines nanotechnology and photonics, mainly focusing on the manipulation, transmission, emission, and detection of light at the nanoscale. It explores how nanomaterials and nanostructures can be used to achieve novel optical properties and functions, such as enhanced light absorption and efficient luminescence. Optoelectronics focuses on the interconversion of light and electrons and the development and application of related devices. When combined with nanotechnology, the performance of optoelectronic devices can be further improved to achieve smaller sizes, higher efficiency, and better functions.

Nanophotonics provides new ideas and technical means for optoelectronics, and the practical demand of optoelectronics has also promoted nanophotonics research. The integration of nanoscale photonics, optoelectronics, and nanophotonics is crucial to the development of many fields, such as the information technology, energy, and biomedicine fields.

This Special Issue aims to collate and present recent research related to nanoscale photonics and optoelectronics, including but not limited to research on computational science and the synthesis, preparation, and applications of nanophotonic and optoelectronic devices. Both original research article and review papers are welcomed to this Special Issue.

We look forward to receiving your contributions.

Vector beams (VBs) with longitudinally varying polarization states provide a new dimension for light field manipulation, and promote the advancements of related areas such as optical metrology, longitudinal depth detection, and classical and quantum communications. In this study, we propose a half-wave plate dielectric metasurface based on a spatial partitioning method, realizing the longitudinal manipulation of the polarization states of higher-order Poincaré (HOP) beams by changing the elliptical polarization state of the incident light and selecting the appropriate propagation distances. The metasurface is composed of two sub-metasurfaces, and the two sets of a-Si:H meta-atoms are uniformly arranged on concentric rings of different radii with an equal interval. The propagation and Pancharatnam–Berry phases are utilized to construct the axicon and helical phase profiles. As a result, two sub-metasurfaces, respectively, generate the first- and second-order VBs with longitudinally varying polarization states. The polarization states of generated VBs correspond to points on different meridians of nth-order HOP spheres from the south pole to the north pole. The consistency between the theoretical and simulated results demonstrates the feasibility and practicability of the proposed method. This study provides an innovative strategy to extend the modulation of light fields from two-dimensional to three-dimensional space. Full article
