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 ...

Fiber-optic waveguide modulators used in communications networks. The modulators, which often require special connectors, work in conjunction with polarization-maintaining (PM) fibers, mostly Panda ...

Richardson, TX—Anritsu Instruments Company, a subsidiary of Anritsu Corporation, a global provider of operational support solutions for advanced and converged networks, introduces its ACCESS Master ...

Interferometers, devices that can modulate aspects of light, play the important role of modulating and switching light signals in fiber-optic communications networks and are frequently used for gas ...

Building integrated-photonic circuits into a new generation of technology requires expanding our view of light guiding to a broad range of optics that transport and manipulate light. What are modal ...

Fiber optic cables have vastly improved our ability to communicate or transmit data over great distances — but a critical flaw has gone unaddressed for the 50-plus years we’ve used them. Glass fibers ...

Waveguides are structures designed to direct and control the propagation of electromagnetic waves from one point to another. They play a crucial role in various fields, including telecommunications, ...
