Special Issue Information

Dear Colleagues,

Optical metamaterials refer to artificially designed structures with dimensions close to or smaller than the wavelength of light that enable the control of light intensity, polarization state, and phase, among other optical properties.

Optical metamaterials are a highly sought-after and broadly applicable cutting-edge frontier technology with applications in fields such as optical fibers, medical devices, aerospace, sensors, infrastructure monitoring, smart solar management, radar antennas, acoustic cloaking technology, terahertz, microelectronics, absorbing materials, holography, and more.

This Special Issue aims to provide a broad overview of the research trends in optical metamaterials, with a particular emphasis on their applications in advanced optoelectronic devices. We cordially invite researchers to submit manuscripts to this Special Issue. Research areas may include (but are not limited to) the following:

  • Metasurfaces;
  • Metamaterials and structured photonic materials;
  • Advanced optics;
  • Low-dimensional structures;
  • Light field regulation;
  • Topological photonics;
  • Quantum metamaterials;
  • Non-reciprocal optics;
  • Nonlinear and ultrafast optics;
  • Metalens.

In the development of optical absorption technology, achieving ultra-wideband high absorption structures that span from the 200 nm ultraviolet C region to the 5800 nm mid-infrared range has been a significant challenge in materials science. Previous studies have shown that few optical absorbers can simultaneously achieve an absorption rate above 0.900 and cover such a vast spectral range. This study presents an innovative seven-layer composite structure that successfully addresses this long-standing technical issue. Through a carefully designed layered architecture, the researchers employed COMSOL Multiphysics (version 6.0) for detailed numerical simulations to verify the optical performance of the structure. The structural design features two key innovations. In the layered composition, the bottom (h1), h3, and h5 layers are made of metallic Fe, while the layers above them (h2, h4, and h6) use SiO2. The top layer is composed of a discontinuous cylinder Ti matrix. The first innovation involves the use of an inwardly recessed square design on the metallic Fe planes of the h4 and h6 layers, achieving high absorption across the 600–5800 nm range. The second innovation involves the use of the discontinuous cylinder Ti matrix for the top layer, which successfully enhances absorption performance in the 200–600 nm wavelength range. This structure not only employs relatively low-cost metals and oxide materials but also demonstrates significant optical absorption potential. Through numerical simulations and precise structural design, this study provides new ideas and technological pathways for the development of ultra-wideband optical absorbers. Full article

When a phosphor film based on a photonic crystal (PhC) is excited at the photonic band-edge wavelength, the absorption of excitation light increases, which can potentially enhance the color-conversion efficiency. In this study, we modeled a two-dimensional (2D) PhC quantum dot (QD) film with a square-lattice structure using the finite-difference time-domain method to theoretically investigate its optical properties. The embedment of a thin-film layer with a high refractive index on the surface of the QD film enables an effective localization of excitation light within the phosphor. A numerical estimation shows that the optimized 2D PhC QD film can enhance the light absorption by up to 4.2 times with a monochromatic source and by up to 1.8 times with a broadband (FWHM~30 nm) source compared to a flat-type reference QD film.
