Abstract

The invention relates to an optical amplifier, in particular for optical-fiber telecommunications lines, comprising an active fiber (7) containing a fluorescent dopant in the respective optical core having emission at the wavelength of the transmission signal to be amplified, into which optical fiber a luminous pumping signal is supplied, in which the active optical fiber (7) is a fiber that in a substantially rectilinear configuration permits the single-mode light propagation at the transmission wavelength and the multi-mode light propagation at the pumping wavelength and is disposed, at least over 70% of the length thereof, in a curved configuration (11) with a bending radius corresponding to the propagation into the fiber itself of the fundamental mode alone at the pumping wavelength,; thereby reducing the mode diameter at the transmission wavelength without however transmitting higher modes for the pumping signal.
