Researchers have fabricated a hair-thin microphone made entirely of silica fiber that can detect a large range of ultrasound ...

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 ...

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 ...

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 ...

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 ...

- 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 ...

The Fiber Optical Homogenizer (Laser Beam Stabilizers) is an all-fiber passive component which can efficiently homogenize speckle pattern and reduce unwanted modal noise (striations, hot spots, and ...

Caltech scientists have developed a way to guide light on silicon wafers with low signal loss approaching that of optical ...

As quantum computers continue to advance, many of today's encryption systems face the risk of becoming obsolete. A powerful ...
