On October 30th, Lumentum announced the acquisition of Hong Kong optical module manufacturer Cloud Light for $750 million (approximately RMB 5.48 billion), with the aim of expanding its influence in cloud data centers and network infrastructure.It is understood that Cloud Light is a Hong Kong company that provides various optical product solutions, mainly focusing on designing and manufacturing ad...
Recently, the Advanced Laser and Optoelectronic Functional Materials Department of the Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, has made progress in the research of Nd: ASL (Sr0.7Nd0.05La0.25Mg0.3Al22.7O19) laser crystals, and the related achievements were published in Infrared Physics&Technology under the title of "Tunable laser operations on Nd doped cont...
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...
Light has angular momentum properties. Circularly polarized or elliptically polarized beams carry spin angular momentum (SAM), while beams with helical phase wavefronts carry orbital angular momentum (OAM). During the interaction between light and particles, the transfer of angular momentum can generate optical torque, driving particles to rotate. Among them, the transfer of optical spin angular m...
An international research team from Leibniz University in Hanover and Strathclyde University in Glasgow overturned the previous hypothesis about the influence of multiphoton components in the thermal field and the interference effect of parameterized single photons. The journal Physical Review Letters published the team's research."We have demonstrated through experiments that the interference eff...
