SpaceX President Gwynne Shotwell stated at a meeting on Tuesday that the company has started selling satellite lasers for fast space communication to other satellite companies.SpaceX's thousands of Starlink satellites in low Earth orbit use inter satellite laser links to transmit data to each other in space at the speed of light, so that the network can provide more extensive Internet coverage wo...
Modern computer chips can construct nanoscale structures. So far, only these tiny structures can be formed on top of silicon chips, but now a new technology can create nanoscale structures in a layer beneath the surface. The inventor of this method stated that it has broad application prospects in the fields of photonics and electronics, and one day, people can manufacture 3D structures on the ent...
In the field of physics, the synthetic dimension has become one of the forefront of active research, providing a way to explore phenomena in high-dimensional space, surpassing our traditional 3D geometric space. This concept has attracted great attention, especially in the field of topological photonics, as it has the potential to unlock rich physics that traditional dimensions cannot reach.Resear...

A novel method is used to deflect the laser beam using only air. The interdisciplinary research team reported in the journal Nature Photonics that invisible gratings made solely of air not only do not suffer damage from lasers, but also retain the original quality of the beam. The researchers have applied for a patent for their method.Technology and PrinciplesThis innovative technology utilizes so...
