    Optical Isolators - (78 companies)
    Optical isolators are optical devices that allow light to be transmitted in only one direction. They are most often used to prevent any light from reflecting back down the fiber, as this light would enter the source and cause feedback problems... Search by Specification | Learn More

Volume holographic gratings (VHG) are diffractive elements consisting of a periodic phase or absorption perturbation throughout the entire volume of the element. When a beam of incident light satisfies the Bragg phase matching condition it is diffracted by the periodic perturbation. Due...

We report on Volume Bragg Grating (VBG) technology for a spectrum of applications in optical components ranging from fixed or tunable filters, ROADM, beam combiners and pump stabilizers. VBGs allow higher integration and added functionality than Fiber Bragg Gratings. Volume Bragg Grating (VBG...

...for harsher motions such as sawtooth-waves. Elimination of structural resonances results in higher-fidelity Bragg gratings: narrower channel widths, higher efficiency. Air-bearing/piezo stage from Dover Instruments Inc., Westboro, Mass., employs vibration nullification in the manufacture of Fiber...

The dramatic reduction in transmission loss of optical fibers coupled with very important developments in the area of light sources and detectors have resulted in phenomenal growth of the fiber optic industry during the last 35 years or so. Indeed,. the birth of optical fiber communication systems...

) but also allowed signal regeneration after 80 km or more. The pace of innovation in all fields of lightwave technology only quickened during the 1990s, as evident from the development and commercialization of erbium-doped fiber amplifiers, fiber Bragg gratings, and wavelength-division-multiplexed...
