Primary performance data for passive fiber-optic devices is provided by spectral measurement of optical insertion loss (IL) and polarization-dependent loss (PDL). Often used to characterize optical ...

Jonathan Ingham and colleagues at the University of Cambridge, UK, have used kilometer lengths of standard optical fiber to demonstrate that changes in photon number states do not induce dispersion ...

Electrical signals control a vast number of activities in the human body, from exchanges of messages between brain neurons and stimulation of the heart muscle to the impulses that enable hands and ...

Researchers have shown that a single photon carrying quantum information can travel down kilometers of noisy real-world fiber ...

Optical engineers require fast optical switches for a variety of purposes without paying huge sums. LASER COMPONENTS offer a range of inexpensive, high reliability ...

Researchers have harnessed the light-guiding properties of spider silk to develop a sensor that can be used to determine concentrations of fructose, sucrose and glucose sugars based on changes in a ...

Thousands of miles of fiber-optic cables, already in place across California, can shake up the study of earthquakes. New research out of Caltech used a section of telecommunication fiber to sense and ...

Scientists hope to employ networks of “dark fibers,” unused fiber optic cables, in order to sense sound waves moving underground—the signals of earthquakes. Some millions of miles of fiber optic cable ...

A fibre-optic acoustic sensor that can detect a person up to 10 m away could soon be deployed in many demanding security applications. Jacqueline Hewett talks to David Hill at QinetiQ to find out just ...

Researchers at Los Alamos National Laboratory have demonstrated that fiber-optic cables buried in simulated lunar soil can ...
