- An optical fiber with 19 cores within a standard cladding diameter was developed, enabling a transmission capacity of 1.7 petabits per second. - Randomly coupled multi-core fibers require less power ...
- The world's first successful petabit-class transmission over more than 1,000 km using standard 19-core optical fiber, achieving a transmission rate of 1.02 petabits per second over a distance of ...
New research is improving the performance of sensors based on fluid-core optical fibers, while also making them easier to fabricate. Tim Hayes reports. Microstructured optical fibers have long held ...
Researchers at VTT, Finland, have been able to transmit light through an optical fiber based on a wood derivative. The fiber, which is made of cellulose, is best suited for sensors that could benefit ...
DARPA has succeeded in creating hollow-core photonic-bandgap optical fiber, which allows light to travel along its length at around 99.7% the speed of light, or a 30% improvement over conventional ...
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 ...
