Recently, the liquid crystal adaptive optics research team from Changchun Institute of Optics, Fine Mechanics and Physics (CIOMP), Chinese Academy of Sciences (CAS) has built a high-density integrated beam array generation system using Liquid Crystal Optical Phased Array (LCOPA). The number of sub-beams in the integrated beam array is 40×40, and the average pointing accuracy is less than 20μrad. This study is published on Optics Communications.
Metal surfaces are vulnerable to pitting and peeling failures in deep seawater due to aggressive corrosive ions, which can hamper their usage for marine applications. Therefore, anticorrosion research on industrial metallic surfaces to avoid the seawater corrosive ion interaction has great life-saving and economic significance.
In recent years, micro-LED displays have attracted increasing research and commercial attention because of their unique advantages, including high resolution, low power consumption, high brightness, and flexibility. In order to meet the application requirements of full-color micro-LED display, it is necessary to optimize the fabrication process to produce high-performance display devices.
Temperature is one of the basic physical quantities. Nowadays, emerging industries are developing rapidly, and it is difficult for existing commercial thermometers to meet the difficult and high-precision requirements of some special applications. Instead, optical temperature sensing solution based on luminescent materials has demonstrated unique advantages in temperature detection.
The preparation of micro/nanostructures is related to multiple applications involving structures such as photonic crystals, metamaterials, and anti-reflective surfaces. Laser-induced periodic surface structures on the variety of solids have been studied extensively due to their scientific interests.
Extraordinary optical transmission (EOT) is the phenomenon of the greatly enhanced transmission of light through a subwavelength aperture in an otherwise opaque metallic film patterned with a regularly repeating periodic structure. The mechanism of EOT is attributed to the scattering of surface plasmon polaritons (SPPs). Tremendous potential applications of EOT include
