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...
The chip based device, known as the frequency comb, measures the frequency of light waves with unparalleled accuracy, completely changing timing, detection of exoplanets, and high-speed optical communication.Now, scientists and collaborators from the National Institute of Standards and Technology in the United States have developed a new method for manufacturing combs, which is expected to improve...
Recently, the UK's national synchrotron "Diamond Light Source" announced an investment of nearly £ 520 million ($648.3 million) to implement three new flagship beam lines and upgrade existing beam lines. This comprehensive upgrade will be delivered by 2030.The Department for Science, Innovation, and Technology and the biomedical charity Wellcome jointly approved the facility upgrade project,...
