http://www.iflscience.com/physics/a-photon-has-been-sent-to-space-using-quantum-teleportation/ Last month, Chinese researchers showed that quantum communication between Earth and space is possible, and now they have used the tech to send a photon to space using quantum teleportation. As this research shows, to create a truly global network for quantum communication, we will need quantum satellites. →
http://spectrum.ieee.org/cars-that-think/transportation/self-driving/under-the-hood-of-luminars-long-reach-lidar Current automotive lidars scan their surroundings by firing pulses from semiconductor diode lasers emitting at 905 nanometers in the near infrared and recording reflected light to build up a point cloud mapping the car’s surroundings. But laser-safety rules in the U.S. and other countries restrict the power in the laser pulse, limiting the lidar’s →
http://www.iflscience.com/space/worlds-brightest-laser-is-literally-changing-how-we-see-things/ This is interesting news: Researchers have used the brightest light source in the world and it’s changing the way we see things. “When we have this unimaginably bright light, it turns out that the scattering – this fundamental thing that makes everything visible – fundamentally changes in nature,” senior author Donald Umstadter, the Leland →
An optical power meter (OPM) is a device used to measure the power in an optical signal. The term usually refers to a device for testing average power in fiber optic systems. Power meters are part of the toolbox essentials for all technicians installing or maintaining any type of fiber networks. They are used to →
The Visual Fault Finder is a visible laser light source used to check continuity, locate breaks, poor mechanical splices and damaged connectors in fiber optic cabling. It can be used to verify continuity, test and find breaks in fibre links, locate pinched fiber strands in termination cabinets, or anywhere fiber optic cables are terminated and →

Pulses of light can leave behind cone-shaped wakes of light, somewhat similar tocone-shaped sonic booms created byaircraft flying at supersonic speeds. Now, a superfast camera has captured the first-ever video of these events. To capture video of these elusive light-scattering events, the researchers developed a “streak camera” that could capture images at speeds of 100 →

Fiber optic cable in essence, is a hair-like glass conduit that carries virtually any type of signal from one point to another at light speed (at the speed of light has in glass, around two thirds of the speed it has in free space). Today, practically every communication network contains fiber optics, because fiber’s extra →
An optical fiber is a flexible, transparent fiber made by drawing glass (silica) or plastic to a diameter typically slightly thicker than that of a human hair. Optical fibers are used most often as a means to transmit light between the two ends of the fiber and find wide usage in fiber-optic communications. Fibers are →
