10th Anniversary of LSA: Collection on Optical Materials, Metamaterials and Photonic Crystals
2022 marks the 10th anniversary of Light: Science & Applications (LSA). In the past decade, LSA has published hundreds of outstanding researches covering the fundamentals and applications in all areas of optics and photonics. From those published papers, we have picked some on Optical Materials, Metamaterials and Photonic Crystals to share with you, our readers. We hope this collection can stimulate more researches and practices in related fields, and promote further progress in optics and photonics research.
Ellipsoidal-shaped Mie resonators are integrated with a liquid crystal cell to demonstrate electrically tunable reflective structural color metasurfaces that can be modulated continuously from bright spectral colors to dark blacks.
Using different chiral precursor molecules, we produced chiral CDs with superior optical properties, such as two-photon absorption, high photoluminescence quantum yield reaching 57%, and chiral signals in the UV-Vis spectral region.
Light momentum inside near-zero refractive index materials is analyzed using Abraham–Minkowski discussion. It explains the absence of fundamental radiative processes, of diffraction patterns or Doppler effect inside such materials.
Summarizing recent advances in the processing and properties of AlGaN-based solar-blind UV photodetectors and focal plane arrays as well as AlGaN growth and doping techniques.
A wide variety of carbon nanomaterials can be grouped under the category of carbonized polymer dots (CPDs) because of their observed structural diversity. Nomenclature is thus proposed for the better identification of various CPDs materials.
Ultra-broadband metamaterials absorbers with high absorption, ultrathin thickness and easy configurations are designed and demonstrated, which pave the way for enhancing the optical performance in applications of infrared thermal emitters, imaging and photodetectors.
The twisted bilayer photonic crystals have near-zero group velocity over the Brillouin zone and provide access to light localization that is far out of the reach of conventional photonic crystals.
Development of a simple yet insightful model to understand the optical behavior of dots-in-host semiconductors. Unprecedentedly shown that quantum-enabled absorption coefficients can reach levels close to that of bulk semiconductors.
