Abstract: An optical signal amplifier with a waveguide path integrated into a glass body (7) that is doped with optically active material. The signal to be amplified is transmitted through the waveguide (1') and the pump power (8) is coupled into the waveguide at one end. The waveguide (1') comprises closely spaced adjacent guide lengths in the form of a spiral, zigzag paths between mirrors (10), or parallel paths with connecting semicircles (12) at alternating ends of succeeding pairs of paths.

Abstract: A device, utilized for the separation or combination of two signals of different wavelengths, of the type in which the waveguides comprise straight interaction segments (11, 21 ; 11n, 21n) parallel and close to one another and to curved approach segments with inflection points (12, 22, 13, 23; 12n, 22n, 13n, 23n), connected to the ends of the straight segments, and, for certain ones, to inputs/outputs (4,5,6) of the device. In accordance with the invention, the approach segments situated on at least the same side of the straight segments are free of any inflection point, the coupling of the straight segments being optionally modified to compensate for the variation of the coupling between the waveguides along said approach segments due to the omission of the inflection points.

Abstract: SUMMARY A splitter is produced by ion diffusion in a glass substrate and it is designed to assure the transmission of an optical signal toward two outputs with a predetermined ratio of the signal power appearing at these 2 outputs. In accordance with the invention, it comprises an X-junction of two rectilinear waveguides defining at their intersection a half-angle .alpha., the angle and the geometry of the central region being chosen in such a way as to establish the predetermined power ratio and the relative achromaticity of the device. Application to MxN couplers.
