According to Korean media reports, Meere, a semiconductor and display equipment manufacturer from South Korea, is continuously expanding its presence in the high stack semiconductor market, including its HBM business.In fact, Meere itself is the world's top manufacturer of display edge grinding mechanisms, with a market share of up to 70%. It is based on its accumulation of display microfabricatio...
Recently, the High Power Laser Physics Joint Laboratory of Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, proposed a single exposure interferometric calibration method for large aperture diffractive lenses, which provides strong support for the engineering application of large aperture diffractive lenses. The relevant achievements are published in Optics Letters as "...
In a groundbreaking scientific study published in Volume 13 of the Scientific Report, researchers reported on the results of Young's double slit interference experiment using oscillating vortex radiation under a photon counting system. The experiment involves using a spiral oscillator to emit second harmonic radiation in the ultraviolet range. Using an ultra narrow bandpass filter in the low curre...
Recently, the Los Alamos National Laboratory (LANL) in the United States has developed a method for quantum light emitters, which stacks two different atomic thin materials together to achieve a light source that generates circularly polarized single photon streams. These light sources can also be used for various quantum information and communication applications.According to Han Htoon, a researc...
