Recently, researchers and their partners from the Fraunhofer Institute for Reliability and Microstructure (IZM) in Germany announced the successful development of a laser welding technology that can efficiently fix optical fibers onto photonic integrated circuits (PICs) without the need for adhesive bonding.This technology is developed in response to biophoton sensing technology, mainly utilizing ...
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...
The Chinese Academy of Sciences reduced the volume of the deep ultraviolet laser by 90% and achieved 193 nm vortex beam output for the first time. Professor Xuan Hongwen described "loading truck equipment into the car trunk". This technology enables a 30% reduction in the size of lithography features, breaking through the bottleneck of the 2-nanometer process. In the next three years, laser power ...
Recently, teachers and students from the Institute of Solid State Laser and Ultrafast Photonics at the School of Physics and Optoelectronic Engineering have made significant progress in the study of ultrafast carrier dynamics in optoelectronic functional crystals. The related research results are titled "Anisotropic carrier dynamics and laser fabricated luminosity patterns on oriented single cryst...
