Title: Non-linear optical device for processing an optical signal, comprising an interferometer with multiple arms

Abstract: Non-linear optical device for processing an optical signal, comprising an interferometer with multiple arms. This device comprises an optical interferometer comprising N arms (B1 . . . BN) where N.gtoreq.3n, N semiconductor optical amplifiers (A1 . . . AN) each being inserted in the N arms, a first optical coupling means (28) that receives a control signal and distributes this control signal into the N arms and a second optical coupling means (32) that receives an input signal and distributes it in at least N-1 of the N arms and collects the light resulting from the distribution of the control signal in the N arms and supplies an output signal which is the resultant of interference of these two light sources. Application to optical telecommunications.
