摘要
Optical device with semiconductor light guide, emerging beam of small divergence, application to Fabry-Perot lasers and distributed feedback. BR/ According to the invention, the heart of the guide of the device comprises at least one first semiconductor layer (8) whose refractive index is greater than that of each of the confinement layers (4, 6) of the guide and at least one second semiconductor layer (10) whose refractive index is less than the refractive index of each of the confinement layers or adjacent to it. BR/ Application to optical telecommunications.
