Abstract
The integrated-optics coupling component is designed to cooperate with a transverse multimode power laser diode () with semi-conductor to form a transverse multimode power laser. It comprises an input zone () connected to at least one output waveguide () by at least two adiabatic tapering zones (). At least two filtering windows () form the inputs of the adiabatic tapering zones () at the end of a diffraction zone defined by the input zone. Reflecting elements, for example a Bragg grating (), can be arranged on the output waveguide. An emitting face () being antiglare-treated, an extended laser cavity oscillating on a single predetermined mode is thus defined between a reflecting rear face () of the laser diode and the reflecting elements ().
