How Fibers Really Work
Feb 13, 2014 — Basic knowledge of fiber optics is widespread – but often infected by certain misconceptions. The basics of fiber optics are seemingly quite simple. Guidance of light in a fiber core can be explained with the physics of total internal reflection, and – at least for step-index fibers – a few simple formulas well describe some essential relations. A closer look, however, often reveals surprising phenomena and shows that some widespread beliefs are not correct. This article
Novel Fibers Use Space to Extend Capacity Limits
Jul 1, 2013 — New optical fibers such as multicore, multimode and hollow core use their spatial properties in the designs of next-generation systems to solve future fiber capacity bottlenecks and other sticky problems. The optical network that enables...
SQUARE Fibers Solve Multiple Application Challenges
Feb 1, 2011 — A square-core optical fiber makes a better match with laser diode output beams, allowing greater coupling efficiency. Square-core fibers also offer advantages over circular fibers in applications such as spectroscopy and laser machining, where...
A New World of Fiber Sensors
Oct 1, 2009 — Optical fiber is well-known for its ability to carry information at high speeds over long distances. Twenty years after the first transatlantic fiber optic cable was laid, these strands of ultrapure glass continue to offer unrivaled bandwidths. They...
Debuts at OFC/NFOEC
SAN DIEGO, Feb. 26, 2008 -- Demonstrations of breakthrough technologies and products by companies such as Lightwire, Finistar, Corning, and JDSU are attracting visitors today to the exposition at OFC/NFOEC 2008 in the San Diego Convention Center. The Optical Fiber...

FiberTech Joins Leoni
Feb 1, 2008 — Leoni Fiber Optics, a subsidiary of the Leoni Group of Nuremberg, Germany, has purchased 90.2 percent of FiberTech GmbH of Berlin. The former says that the acquisition will increase its portfolio of specialty fibers, as FiberTech is a producer of...
Lasing in a Gain-Guided, Index-Antiguided Fiber
Jul 1, 2007 — In the past decade and a half, fiber lasers with very high multimode output powers have been developed by doping the core of such fibers with ions that can lase. These fiber lasers are pumped by light from diode-laser arrays that is coupled into...
NeoPhotonics Buys BeamExpress
SAN JOSE, Calif., Sept. 5, 2006 -- NeoPhotonics, a global supplier of fiber-optic component and module solutions for long haul, metro and fiber-to-the-x (FTTx) networks, announced today it is acquiring BeamExpress Inc. of Sunnyvale, Calif. Terms of the deal were not disclosed....
