The D-Series of Optical Time Domain Reflectometer (OTDR) solutions from EXFO are advanced field testing tools that deliver highly accurate measurements to characterize and validate fiber links. ...

Laser diodes vary widely in their wavelengths, powers, spectra and beam quality. Yet they share two fundamental components with all other lasers: an optical amplifier and a resonator that confines...

Optical fibers are made from either glass or plastic. Most are roughly the diameter of a human hair, and they may be many miles long. Light is transmitted along the center of the fiber from one end...

As system and cable installers try to optimize their links, the preferred method has become high-speed DWDM. This demand for bandwidth has led to the development of new test and measurement...

Dual-comb ranging (DCR) is a powerful optical metrology technique capable of absolute distance measurements at high-precisions and rapid update rates. Unfortunately, data analysis usually requires...

Lasers with large beam divergence are used in a number of applications, such as remote sensing, optical communications, and materials processing. Large beam divergences create challenges for reliably...

Plasmonics, or the investigation and manipulation of electron oscillations along metal–dielectric interfaces, is an emerging technology with great innovation potential. Biophotonic sensing,...

The light source of a widefield fluorescence microscope is often overlooked by scientists setting out to capture fast cellular processes with live cell imaging. But LEDs have changed the game. ...

A receiver for optical communications systems consisting of a symmetric binary, pulse-code-modulated transmitter, a log-normal channel and an array of independent photocounting detectors that yield...

A laser, which stands for "light amplification by stimulated emission of radiation," is a device that produces coherent and focused beams of light through the process of optical amplification based...

A fiber laser is a type of laser in which the active gain medium is an optical fiber doped with rare-earth ions such as erbium, ytterbium, or neodymium. Fiber lasers generate coherent light through...

A MEMS fiber optic switch is a microelectromechanical system (MEMS) device designed to selectively route optical signals between multiple fiber optic channels. These switches utilize miniature...

On this week’s show we’ll discuss how optogenetics is advancing sleep research, and how lasers are helping speed up satellite transmissions. But first we’ll learn about a government program fueling...
