Conventional curved lenses, which direct light by refraction in glass or plastic, are often bulky and heavy, offering only limited control of light waves. Metasurfaces, in contrast, are flat and ...

Abstract: Semiconductor laser external cavity spectral beam combining (SBC) technology has been proven to be an effective method to improve the beam quality and output power of the output beam.

Scientists have demonstrated that negative refraction can be achieved using atomic arrays -- without the need for artificially manufactured metamaterials. Scientists have long sought to control light ...
