5d80d7912b Paschotta, case study on an erbium-doped fiber amplifier R. This high-powered light beam excites the erbium ions to their higher-energy state. Acronym: EDFA Definition: fiber amplifiers based on erbium-doped optical fibers German: erbiumdotierte Faserverstrker Categories: optical amplifiers, lightwave communications, fiber optics and waveguides, photonic devices How to cite the article; suggest additional literature Erbium-doped fiber amplifiers are the by far most important fiber amplifiers in the context of long-range optical fiber communications; they can efficiently amplify light in the 1.5-μm wavelength region, where telecom fibers have their loss minimum.

Here, you can use the full-text search function for the whole RP Photonics website. As the pump absorption efficiency can be weak in this case, an ytterbium-sensitized core may again be useful. Profit from the knowledge and experience of a top expert! Powerful simulation and design software. Erbium-doped double-clad fibers can be used for generating very high output powers of tens of watts or even more. Ytterbium ions may then be excited e.g. Photons are emitted spontaneously in all directions, but a proportion of those will be emitted in a direction that falls within the numerical aperture of the fibre and are thus captured and guided by the fibre. HTTP Status 404 - . Quantum Electron. The most common example is the Erbium Doped Fibre Amplifier (EDFA), where the core of a silica fibre is doped with trivalent erbium ions and can be efficiently pumped with a laser at a wavelength of 980 nm or 1,480nm, and exhibits gain in the 1,550nm region.
