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...
The optical properties of photonic crystals are closely related to their lattice constants, which are usually required to be in the same order of magnitude as the operating wavelength. In a crystal material, the photonic crystal structure is formed by the periodic arrangement in space of units whose dielectric constant is different from that of the crystal itself, and whose lattice constant depend...
Recently, a Japanese research team has developed a vertical deep ultraviolet emitting semiconductor laser device based on AlGaN, which is expected to be applied in laser processing, biotechnology, and medical fields.As is well known, ultraviolet (UV) is an electromagnetic wave with a wavelength range of 100 to 380nm. These wavelengths can be divided into three regions: UV-A (315-380 nm), UV-B (280...
Recently, two leading UK scientific institutions, Diamond Light Source and National Physical Laboratory (NPL), have reached a new five-year agreement to promote joint collaborative efforts.The agreement was approved by signing a Memorandum of Understanding (MoU), which will bring these two institutions together.Diamond Light Source is a national synchrotron facility in the UK known for generating ...
