Spectroscopic ellipsometry is widely adopted in semiconductor processing, such as in the manufacturing of integrated circuits, flat display panels, and solar cells. However, a conventional spectroscopic ellipsometer, as shown ...
The diffraction of light is a ubiquitous phenomenon in nature where waves spread out as they propagate. This spreading of light beams during propagation limits the efficient transmission of energy and information. Therefore, ...
Dielectric metasurfaces represent one of the cutting-edge research and application directions in optics. They not only possess the advantage of low loss but also enable the realization of device thicknesses at subwavelength ...
Researchers from Huazhong University of Science and Technology proposed a pixelated programmable photonic integrated circuit (PICs) with record-high 20-level intermediate states of phase change materials (PCMs).
Plasmonics is playing a crucial role in advancing nanophotonics, as plasmonic structures exhibit a wide range of physical characteristics that are benefited by localized and intensified light-matter interactions. These properties ...
Researchers have made a significant breakthrough in controlling the polarization of light, a crucial property for various applications such as augmented reality, data storage, and encryption.
The idea of objects seamlessly disappearing, not just in controlled laboratory environments but also in real-world scenarios, has long captured the popular imagination. This concept epitomizes the trajectory of human civilization, ...
A material coating, whose light refraction properties can be precisely switched between different states, has been developed by an interdisciplinary research team from the Chemistry and Â鶹ÒùÔºics departments at the University ...
Research by Dr. Ruiwen Shao and Prof. Junwei Wu (Institute of Electromagnetic Space, Southeast University, Nanjing, China) teaches us about how digital metasurfaces lose information.
Recently, a research team from Pohang University of Science and Technology (POSTECH) has employed metasurfaces to fabricate angle-dependent holograms with multiple functions. This technology allows holograms to display multiple ...
