fiber Bragg gratings News
Prospects Abound for Photonics in Space
May 12, 2017 — For European companies, the space market has always been a key avenue for photonics technologies. That’s due in large part to the relatively short time to market using the tender system enabled by the European Space Agency (ESA), the ability...
Fiber Laser Welding Cuts Costs and Improves Results
Apr 12, 2017 — Most traditional — i.e., nonlaser — welding techniques currently in use are variations of arc welding. In these methods, two pieces of metal are first brought into contact or close physical proximity. The edges of the pieces may have...
Defense and Aerospace
Nov 22, 2016 — When it comes to spacecraft, planes and military gear, weight is all important. That’s understandable, as it costs about $10,000 to put a pound in orbit, in the case of spacecraft. For planes and military gear, there are limits on what can be...
For Compactness and Ruggedness, Linear Variable Filters Fit the Bill
Jul 29, 2016 — Spectroscopic optical applications have conventionally utilized dispersive elements such as diffraction gratings and, less commonly, prisms to separate light into its constituent wavelengths for spectral interrogation. Gratings have the advantage in...
The Connected World: Banking on Innovations in Photonic Sensors
Apr 28, 2016 — The Internet of Things (IoT) is about to change how we live in almost every conceivable way, from driverless cars and smart cities to precision agriculture. In fact, the economic impact per year of all things IoT is projected to be $11.1 trillion a...
Fiber optic sensors set sail
Sep 1, 2012 — To win races through wind, waves and inclement weather, sailors need nerves of steel. But it turns out that their boats need “nerves of glass.” A new fiber optic sensor system for racing yachts could alert crew members when a craft...
Fiber Optics Pioneer Dies
BROOKLINE, Mass., May 29, 2012 — Laser pioneer Dr. Elias Snitzer, inventor of the glass laser, the fiber laser and the fiber amplifier, died on May 21 after a sudden illness. He was 87.
Plescia, Johnson Join FBGS
GEEL, Belgium, April 5, 2012 — To support its growth into Europe and North America, the fiber Bragg gratings manufacturer appointed Nick Plescia and David Johnson to coordinate and support commercial activities in these regions.
Proximion Opens New Plant
Jun 1, 2011 — In Sweden, Proximion Fiber Systems AB, based in Stockholm, has opened a production facility in Kista in response to increased demand for its dispersion compensation modules based on fiber Bragg gratings. The new plant will allow the company to...
Proximion Opens Plant in Sweden
KISTA, Sweden, March 4, 2011 — Proximion Fiber Systems AB announced the opening of new production facilities in Kista in response to increased demand for its dispersion compensation modules (DCMs) based on fiber Bragg gratings (FBGs). The new plant will allow the company to...
Microspectrographs enable deeper space exploration
SYDNEY, Australia – As telescopes get bigger and bigger – and more complex – engineers and astronomers recognize that simply scaling up existing technology would result in instruments that are limited by size and complexity. Integrated devices for...
Vytran to Showcase FAS at OFC/NFOEC
MORGANVILLE, N.J., March 22, 2010 - Vytran LLC will demonstrate a range of fiber processing equipment, including its fully automated FAS fusion splicing workstation, at the Optical Fiber Communication Conference and Exposition/National Fiber Optic Engineers Conference 2010 (OFC/NFOEC)...
Fiber laser reaches record length
BIRMINGHAM, UK – In a bid to push the boundaries of laser science, a team of scientists from the UK, Spain and Russia has built the longest-ever fiber laser cavity. The group’s aim was to find out just how long it could make a fiber laser cavity in which lasing with...
Fiber Makes Inroads in Stress/Strain Measurement
Dec 1, 2007 — Demand for increasingly sophisticated measurement tools is on the rise in oil and gas as well as in civil-structure industries, among others. Traditional test equipment has included strain gauges and load cells, but fiber optic technologies recently...
Grating Is Written Directly into Ytterbium-Doped Silica Fiber
Aug 1, 2007 — Fiber Bragg gratings (FBGs) are frequently used as the reflectors on fiber-laser resonators. These gratings are written in photosensitive fibers that are fused onto the doped-silica fiber that provides the laser gain. Making the fusion joints...
Electrically Tunable Bragg Gratings in Polymer Fiber
Mar 1, 2007 — The capability of fiber Bragg gratings to reflect only resonant wavelengths while transmitting all others has found numerous applications in telecom, optical sensing and other technologies. Because the resonant wavelengths can be shifted by heating...
Femtosecond Pulses Write Grating in Nonphotosensitive Fiber
Oct 1, 2006 — Although fiber Bragg gratings can readily be written in photosensitive fibers with ultraviolet radiation, it is far more difficult to write them in the rare-earth-doped fibers that comprise all fiber lasers. As a result, the gratings that serve as...
Michelson Interferometry Interrogates Fiber Bragg Grating Sensors
Oct 1, 2003 — Fiber Bragg gratings, which have had such success in wavelength division multiplexing for telecommunications, also have been adapted to environmental sensors. These sensors measure parameters such as temperature, pressure and strain, which cause...
Fiber Bragg Gratings Filter WDM Signals
Mar 1, 2003 — Fiber Bragg gratings are versatile wavelength filters for multiplexing and demultiplexing wavelength division multiplexing (WDM) signals. They also can compensate for chromatic dispersion that can degrade the quality of the WDM signal in an optical...
Sabeus Photonics Inc.
Jan 1, 2003 — Cold writing technology allows sensors to be written directly into a fiber's core without compromising its integrity, tensile strength or durability. The technique does not require stripping and recoating the fiber, and it eliminates the need for...
