Recently, in order to improve the National Aeronautics and Space Administration (NASA) space communications capabilities, NASA plans to send a technology demonstration called "Integrated LCRD Low Earth Orbit User Modem and Amplifier Terminal (ILLUMA-T)" to the space station in 2023.ILLUMA-T and the Laser Communications Relay Demonstration (LCRD), launched in December 2021, will together comp...
IntroductionVortex beams carrying orbital angular momentum (OAM) are widely used for high-throughput optical information multiplexing, and achieving on chip, small-scale vortex lasers is crucial for promoting the industrial implementation of vortex light reuse technology. Recently, Gu Min, an academician of Shanghai University of Technology, and Fang Xinyuan, an associate professor of Shanghai Uni...
For centuries, people have known that light exhibits wave like behavior in certain situations. When light passes through certain materials, they can change the polarization of light waves (i.e. the direction of oscillation). The core components of optical communication networks, such as optical isolators or photodiodes, utilize this characteristic. This type of component allows light to propagate ...
