Objectives of security in civil aviation are reached in multiplying separated measuring chains. The use of dissimilar measuring chains is now encouraged. For this purpose, THALES Avionics has developed an aircraft speed laser anemometer. The suitability of integrated optics on glass for the miniaturisation of the system has been proven in 2006. This thesis aims at pushing ahead with the miniaturisation in hybridising the pump laser diode which supplies the seed laser on a glass platform. The structure consists on locking the fundamental of a Broad Area Laser Diode (BALD) thanks a planar external cavity, composed of a modal converter made by ion exchange on glass and a Bragg grating. First, easy to use conception rules for the BALD's optical feedback are elaborated. Then, the technique of selective field assisted ion exchange is shown to be adapted to the realisation of a modal converter between the BALD and a single mode collecting optical fibre. The realised converter demonstrated the modal locking thanks to the use a fibre Bragg grating. The BALD has been stabilized around the Bragg wavelength with a spectral width of 0.3 nm and stable single mode output power has reached 100 mW. The Bragg grating has then been integrated on the optical chip and the integrated locking of the BALD has been achieved. The output power has been limited by the high reflectivity of the grating. As perspectives, the increase of the output power has been studied and a highly integrated system of intra cavity pumping is proposed.
