INTEGRATED-OPTICS COUPLING COMPONENT, DESIGNED TO ADAPT A LIGHT SOURCE TO A GUIDED OPTICS ELEMENT AND POWER LASER COMPRISING SAME

摘要

The invention concerns an integrated-optics coupling element designed to co- operate with a transverse multimode power laser diode (2), with semiconducto r for forming a transverse monomode power laser. It comprises an input zone (4 ) connected to at least an output waveguide (6) by at least two adiabatic tapering zone (5). At least two filtering windows (7) constitute the inputs of the adiabatic tapering zone (5) at the end of a diffraction zone defined by the input zone. Reflecting elements, for example a Bragg grating (12), can b e arranged on the output waveguide. By providing an emitting surface (3) with antiglare treatment, an extended laser cavity is thus delimited oscillating in a single predetermined mode between a reflecting rear surface (11) of the diode and the reflecting elements (12).
