ABSTRACT:
Optical semiconductor light guide device having a low divergence emergent beam, application to Fabry-Perot and distributed feedback lasers. According to the invention, the core of the guide of the device comprises at least one semiconductor layer (8), whose refractive index is higher than that of each of the confinement or cladding layers (4, 6) of the guide and at least one second semiconductor layer (10), whose refractive index is lower than that of each of the confinement or cladding layers or close thereto. Application to optical telecommunications.
