Since the 1960s, lasers have brought revolutionary changes to the world and have now become an indispensable tool in modern applications, from cutting-edge surgical procedures and precision manufacturing to fiber optic data transmission. However, with the increasing demand for laser applications, challenges have also arisen. For example, the market for fiber lasers is constantly expanding, mainly ...
Researchers at the National Institute of Information and Communication Technology in the United States have invented a new structure of a superconducting strip photon detector that can achieve efficient photon detection even in wide strips, and have successfully developed the world's first superconducting wide strip photon detector.The band width of the detector is more than 200 times that of trad...
Japanese and Swiss scientists have collaborated to develop glass that can generate electricity under light, which may pave the way for sustainable energy production. Researchers from Tokyo Institute of Technology and the Swiss Federal Institute of Technology in Lausanne used femtosecond lasers to etch circuits on glass surfaces, resulting in the unexpected generation of semiconductor crystals.The ...
Recently, the team of Situ Guohai and Guo Jinying from the Aerospace Laser Technology and Systems Department of the Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, and the School of Microelectronics at Shanghai University collaborated to propose a terahertz phase controlled programmable metasurface design scheme based on free carrier plasma dispersion effect. The rela...
Optical metamaterials are an effective way to utilize their superior photon capture capabilities. Therefore, perfect absorbers can be achieved through nanoscale resonant plasmas and metamaterial structures.Metamaterial perfect absorbers (MPAs) are typically composed of periodic subwavelength metals (such as plasma superabsorbers) or dielectric resonance units. Compared with static passive physical...
