Satellite brightness will affect everyone on Earth The number of satellites being sent into LEO is merely one aspect of the problem—an equally important one is the brightness of the satellites. “As long as they’re fainter than magnitude 7 (a weird astronomical unit for brightness; mag 7 corresponds to the brightness of the faintest star

In this edition of Following the Photons’ Light News: Researchers at the University of Rochester’s Institute of Optics have developed a solar-thermal process for turning ocean water into fresh drinking water, using little energy and no chemical additives. Researchers in Austria have made a notable advance with its groundbreaking broadband UV dual-comb spectrometer, in the

The immense success of quantum mechanics can be routinely experienced via the transistor, the laser, nuclear magnetic resonance (NMR), and magnetic resonance imaging (MRI), the atomic clock, quantum tunneling, and more contemporaneously via quantum entanglement, quantum cryptography, and quantum computing. These are massive, tangible, technological contributions. But criticisms toward quantum mechanics as a physical theory

In this episode, host Justine Murphy talks with Dr. Talya Vaknin, head of research at LightSolver, a company specializing in laser-based computer processing. They discussed her work and experiences in the industry, as well as her passion for enriching the world via technological advancements.  Following the Photons: A Photonics Podcast dives deep into the fascinating

One year after the NSF-DOE Vera C. Rubin Observatory stunned us with its first look imagery, the 10-year Legacy Survey of Space and Time (LSST) is officially underway. Atop Cerro Pachón in the Chilean Andes (elevation: ~2,682 meters/8,799 feet), Rubin’s 8.4-m Simonyi Survey Telescope will use a 3,200-megapixel camera to observe the southern sky every few

Optical frequency combs (OFCs) are precise laser light sources whose spectra consist of a series of equally-spaced frequency lines that resemble the teeth of a comb. As highly accurate rulers for measuring optical frequencies, OFCs have revolutionized precision measurement and metrology since their development in the late 1990s. One of the most important capabilities enabled

In this episode of Photonics Hot List: Researchers in Austria have made a notable advance with its groundbreaking broadband UV dual-comb spectrometer, in the form of a compact device. Business news roundup: Keysight Technologies has acquired VPIphotonics, in a move meant to strengthen their capabilities. And integrated photonics developer Jenoptik Optical Systems has named its

Modern precision optical instruments are increasingly limited not by light sources, electronics, or vibration isolation but by the microscopic thermal motion of mirror coatings that form the reflecting surfaces of optical cavities. In optical atomic clocks, ultrastable lasers, stabilized frequency combs, and gravitational-wave detectors, this inherent thermomechanical noise from multilayer mirror coatings sets a noise
