A team of computer and electrical engineers at UC Santa Barbara, in collaboration with several colleagues at Caltech and another colleague at Anello Photonics, has developed a first-of-its-kind chip that can carry both laser and photonic waveguides. In a paper published in the journal Nature, the team describes how they made the chip and how it worked during testing.With the advent of integrated c...
Using light beams for communication is not a new idea, even outside of Star Trek, Star Wars, and other similar fantasy stories. Scientist and science fiction writer Arthur Clark predicted that beam communication, at that time modern satellite communication was just a dream.In 1975, the magazine published an article about laser communication or laser communication equipment. The demonstrati...
Supercontinuum spectrum laser developer SuperLight Photonics has launched the so-called "first revolutionary portable broadband laser" - SLP-1000. Its wide spectral output provides a light source for industrial and medical imaging applications as well as spectroscopy.Supercontinuum spectrum lasers, also known as broadband lasers, provide high bandwidth while maintaining high coherence and low nois...
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...
Aluminum alloy has unique advantages such as lightweight, high strength, and excellent corrosion resistance, and is highly favored in the aerospace manufacturing field. Laser Coaxial Fusion Additive Manufacturing (LCWAM) adopts beam shaping technology, which uses wire as the deposition material to melt and stack layer by layer. Compared to traditional side axis wire feeding technology, laser coaxi...
