ABSTRACT:
To increase the pump efficiency in a fiber-optic amplifier, the pump coupler (2) is fabricated from a fiber whose mode field diameter for the pump light is adapted to the mode field diameter of the active length of fiber (7).
In an alternative solution, the arm of the pump coupler (2) coupled to the pump source (1) on the one hand and connected to the active length of fiber (7) on the other hand consists of a fiber adapted to the mode field diameter of the active length of fiber (7), and the arm of the pump coupler (2) serving as a connection to the incoming transmission line (8) consists of a fiber corresponding to the optical waveguide of the transmission line (8).
