A large group of fiber optic lasers are powered by DC current. Laser drive is supplied by a current source with modulation added further along the signal path. The current source, although ...

Quantum dots with precise crystal growth and advanced processing enable compact, energy-efficient, and cost-effective light sources for optical fiber communications. (Nanowerk News) The National ...

Thulium fiber lasers, operating at a wavelength of 2 micrometers, are valued for applications in medicine, materials processing, and defense. Their longer wavelength makes stray light less damaging ...

For the first time, researchers have shown that 3D-printed polymer-based micro-optics can withstand the heat and power levels that occur inside a laser. The advance enables inexpensive, compact, and ...

Free-space optical communications (FSOC), which use lasers for data transmission, are a promising approach for achieving high-speed links between aircraft, spacecraft, and ground stations. However, ...

One of the next big upgrades in telecom will involve satellites firing lasers at each other—to beam data, not blow stuff up. The upside of replacing traditional radio-frequency communication with ...

Laser cutting and engraving technologies have become essential tools across a wide variety of different industries, from manufacturing, art and small businesses. These technologies use laser beams to ...

Telecommunications as an industry is often bogged down by technological inertia. Various regulations and dependencies mean that new innovations often don’t come to market for close to a decade, and ...

The common reason for distressed earnings is, “higher labor costs.” Yes, humans have an upper hand in discretionary tasks, but recurring industrial tasks like welding, etching and cutting can be ...
