Optical amplifier with a doped fluoride glass of optical fibre and process for producing said amplifier

摘要

Optical amplifier with a doped fluoride glass optical fibre and process for the production of said amplifier.PPIn said amplifier, two monomode silica fibres (4a, 6a), whereof at least one is doped with erbium, are coupled to two ends of an erbium-doped, fluoride glass monomode fibre (2) and have the same optical mode diameter as the latter. Application to optical telecommunications.
