- Development of the world's first practical surface-emitting laser suitable for optical fiber communications systems. - Utilization of quantum dots as an optical gain medium, enabled by NICT's ...

Australian-US team says wavefront-shaping of input light lifts power threshold for SBS scattering by an order of magnitude. A narrowband laser beam shaped by a spatial light modulator excites many ...

A new publication from Opto-Electronic Advances; DOI 10.29026/oea.2024.240105, discusses a high-resolution tumor marker detection based on microwave photonics demodulated dual wavelength fiber laser ...

It’s a rare person who can pick up a cheap laser pointer and not wield it like a lightsaber or a phaser, complete with sound effects. There’s just something about the “pew-pew” factor that makes ...

Femtum, a Quebec City startup that has developed short-pulsed mid-infrared fiber lasers, says it has closed a round of series ...

Fiber-optic cables on the moon could detect moonquakes, offering a simpler way to study lunar activity and support future ...

Scientists have successfully miniaturized a powerful erbium-based biber laser on a silicon-nitride photonic chip. Since typical erbium-based fiber lasers are large and difficult to scale down, the ...

Tubular laser beams can create what amount to fiber-optic cables made of thin air, researchers report in a study to appear in Physical Review X. Laser-heated air can efficiently transmit light signals ...

From 1970 to today, the clarity of fiber has continued to improve, becoming over 100 times clearer now and allowing networks to connect the world. For “groundbreaking achievements concerning the ...

Patients who remain in bed for long periods of time may develop pressure sores, which can in turn become potentially life-threatening chronic skin ulcers. A new sensor could help keep that from ...
