Recently, a team led by Gao Chunqing and Fu Shiyao from the School of Optoelectronics at Beijing University of Technology combined optical spatial coordinate transformation with photon spin Hall effect to construct a photon angular momentum filter for the first time internationally, achieving on-demand regulation of photon spin angular momentum and orbital angular momentum.The related achievements...
When scientists discovered that laser pulses can rapidly cause refractive index changes in the medium, resulting in "photonic time crystals (PTC)" in the near-visible light band, the door to a disruptive new application in optics seemed to quietly open.Scientists have a certain degree of understanding of photonic crystals and time crystals, the two have almost nothing in common, the basic common p...
Gallium nitride (GaN) vertical cavity surface emitting laser (VCSEL) is a semiconductor laser diode with broad application prospects in various fields such as adaptive headlights, retinal scanning displays, nursing point testing systems, and high-speed visible light communication systems. Their high efficiency and low manufacturing costs make them particularly attractive in these applications.Gall...
The research team used a new reverse design framework to demonstrate ultra optical broadband thermal imaging for applications ranging from consumer electronics to thermal sensing and night vision.The new framework, known as the "Modulation Transfer Function" project, solves the challenges related to broadband metaoptics by determining the functional relationship between image contrast and spatial ...
The latest research led by the University of Surrey shows that alumina (Al2O3) nanoparticles can significantly enhance the lifespan and stability of perovskite solar cells, extending the service life of such high-efficiency energy devices tenfold.Although perovskite solar cells have advantages such as low cost and light weight compared to traditional silicon-based technologies, their commercial po...
