Abstract: An optical fiber (30) is interfaced with an optical device (12) formed on a substrate (10). The substrate includes a groove (22) under and behind an interface between the optical fiber (30) and the optical device (12). Provision of such a groove (22) allows the substrate (10) to be used for alignment and support of the optical fiber (30), while reducing fusion loss and improving durability of the interface. Steps for facilitating alignment may be provided in the substrate (10). Solder may be used to further improve durability of the interfaced structure.

Abstract: A fusion joint between a waveguide (1a) and an optical fiber (2) is created by irradiating the interface (4) between the optical fiber and the waveguide using a laser beam. The spatial distribution of the energy furnished to the interface presents a central zone of which the energy is reduced with respect to a peripheral zone, whereby to enable a relatively high energy laser to be used while avoiding bending of the waveguide. The laser beam is caused to irradiate a higher energy density upon the waveguide than the optical fiber, typically by offsetting the center of the laser beam towards the waveguide. The fusion is performed while a force F urges the waveguide and optical fiber towards one another, so as to avoid the creation of a void at the boundary. A supplementary polymer or mineral joint can be provided. A method for multifiber fusion pigtailing more than a single optical fiber to respective waveguiding regions in a planar waveguide includes using a diffractive optical element (130) to produce a multiple energy distribution.

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.
