Billions of years ago, in a distant galaxy, two black holes collided, triggering one of the most extreme cosmic events in the universe. The power of this phenomenon is so great that it distorts the structure of spacetime, emitting ripples called gravitational waves.These waves will eventually be detected on Earth by the Advanced Laser Interferometer Gravity Wave Observatory (LIGO) detector, and te...
Professor Zhang Huaijin and Yu Haohai from the Institute of Crystal Materials of Shandong University (the State Key Laboratory of Crystal Materials) proposed a spatial harmonic modulation strategy, which realizes the phase matching conditions that can be manipulated artificially in the new quartz crystal, and realizes the effective frequency doubling within the VUV range. The relevant research is ...
Recently, according to the journal Nature Nanotechnology, a team from the California Institute of Technology reported that they have constructed a metasurface covered with micro adjustable antennas that can reflect incident light beams: one beam of light enters and multiple beams of light exit, each with a different frequency and propagating in a different direction. This is a new method for proce...
Recently, Sivers Semiconductors, a well-known chip and integration module supplier in Sweden, announced that its subsidiary Sivers Photonics is partnering with ecosystem partners to showcase its advanced laser chip and array technology at the OFC conference in Santiago.The first on-site demonstration used Ayar Labs optical I/O and CW-WDM MSA compatible SuperNova ™ The light source is powered...
The manufacturing of sensors through 3D printing combines speed, design freedom, and the possibility of using waste as a substrate. In the circular economy model, various results have been achieved, and typically discarded residues are used as low-cost resources. A research team in Brazil has proposed a highly creative solution that involves printing electrochemical sensors on fallen leaves. The t...
