In theory, EDFAs are extremely simple — just a loop of doped fiber 10 to 20 meters in length, a laser diode for pumping, and the necessary optical components to join the amplifying loop to the ...

This new optical fiber with a self-cleaned beam can help in developing applications to, for example, tagging pollutants, cancer diagnostics, environmental monitoring, and food control.

The system uses a special type of optical fiber, developed in the University of Southampton optical fiber drawing towers, called “flat fiber.” Flat optical fiber does not have a circular cross-section ...

Perhaps fiber optics will finally bring their hidden processes into the light. 10.1146/knowable-112222-3 Carolyn Wilke is a Chicago-based freelance science journalist.

Physicists at the University of Bath, UK, have developed a new kind of optical fiber designed to enhance the robustness of communications networks.They say that this robustness “could prove to be ...

Unlike regular optical fibers, the speciality fibers fabricated at Bath have a micro-structured core, consisting of a complex pattern of air pockets running along the entire length of the fiber.

Researchers have developed a new optical sensor that provides a simple way to achieve real-time detection of extremely low levels of arsenic in water.

For anyone wondering, the difference in price getting a precision lens versus a “it works for this” lens. The “$31 spherical lens” are far closer to being perfect spheres and their optical ...

Optical fiber is a strand of glass that’s been “drawn,” or melted down, to about as thin as a human hair. Light passes through this glass carrying data, providing an internet connection.

A team of international researchers say they’ve set a new world speed record for an industrial standard optical fiber that’s as thick as a human hair and contains a groundbreaking 19 cores.
