Abstract: A laser source includes a first optical element and a second optical element spaced apart from each other and defining a laser cavity therebetween. The laser cavity with a lasing material therein are capable of emitting an optical beam. The laser source also includes a guided optical element formed on a substrate. The guided optical element includes a mirror which is concave in at least one guide plane of an input guide area of the guided optical element. The mirror forms an extended laser cavity with the laser cavity. The guided optical element also includes a microguide associated with an optical output of the laser source. The microguide defines an output area of the guided optical element. The input guide area is capable of receiving the optical beam emitted by the laser cavity and capable of transmitting the optical beam to an adaptor guide area located between the input guide area and the microguide. The adaptor guide area is capable of guiding the optical beam to the microguide.

The third zone ensuring an optical confinement and a light guidance, and having a composition which varies continuously from a first face to a second face with a gap which increases from the first face to the second face, the first face of the third zone being in contact with the active emission zone. A fourth zone constitutes a buffer zone which contacts the second face of the third zone and a substrate, the fourth zone serving as an optical barrier for light guiding, the first and third zones being asymmetrical with respect to the active emission zone to define an asymmetrical GRINSCH structure, one of the first and third zones constituting a surface of the semiconductor heterostructure for ensuring electron excitation and creation of electron-holes.
