Abstract
The present invention relates to a variable coupler for optical fibers, which can also operate as a mixer. This variable coupler comprises an optical system which concentrates the divergent radiation issuing from the output orifice of a transmitter fiber, on the input orifice of a first receiver fiber, and optical means (flat mirror, prism, plate with parallel faces, for example) capable of performing a translatory motion, which make it possible to intercept a variable fraction of said radiation and direct it on to the input orifice of a second receiver fiber.
