Researchers have built a microscopic 3D-printed optical device that funnels light from 37 separate multimode semiconductor lasers into a single optical fiber, merging 222 distinct spatial modes; the ...

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 ...

EXFO’s Olivier Côté digs into testing challenges — and outlines how methods are evolving to accommodate hollow core fiber's ...

Some of the most revealing signals about human health are carried in fluids that are almost impossible to measure.

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 ...

They may look unconventional but the photosensitive fibre structures being developed at MIT promise a new way to measure the amplitude and phase of an optical signal. Rob van den Berg talks to the ...

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 ...

Arden Photonics is pleased to announce the introduction of the FGC range of optical fiber geometry measurement equipment. The FGC range provides high speed automated measurement of fiber end-face ...

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 ...
