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...
In a significant advancement in material physics, researchers from Germany and the United States have theoretically demonstrated that only extremely thin materials need to be α- RuCl3 can be placed in an optical cavity to control its magnetic state.This discovery may pave the way for new methods of controlling material properties without the use of strong lasers.The Role of Optical Vacuum W...
According to relevant media reports, a research team from the Helmholtz Center in Berlin, Germany, and Humboldt University has jointly developed a new type of perovskite stacked battery. This battery has broken the world record for similar batteries with a photoelectric conversion efficiency of 24.6%. In the solar cell family, in addition to silicon-based solar cells, there are also thin-film so...
Lightmatter, a Boston-based startup developing silicon photonics hardware aimed at AI and high-performance computing, has announced a 16-wavelength bidirectional Dense Wavelength Division Multiplexing optical link operating on one strand of standard single-mode (SM) fiber.Powered by Lightmatter’s Passage interconnect and Guide laser technologies, this development “shatters previous limitations in ...
Haylo Labs, a UK company recently established by former WaveOptics CEO David Hayes, has acquired microLED developer Plessey Semiconductors.Haylo says it also plans to invest more than £100 million scaling Plessey’s production capacity over the next five years at the firm’s GaN-on-silicon site in Plymouth and beyond, in anticipation of fast-growing demand for augmented and virtual reality (AR/VR) a...
