Les lasers à cavité verticale émettant par la surface (VCSEL) à base d'antimoniures dans le moyen infrarouge permettent le développement et l'amélioration d'applications telles que la détection de gaz polluants. De nouveaux miroirs à réseaux à haut contraste d'indice (HCG) ont montré un pouvoir réflecteur comparable voire supérieur aux miroirs de Bragg conventionnels avec un gain d'épaisseur d'un facteur 10 tout en offrant un effet polarisant. L'insertion de ce nouveau type de miroir au sein d'une structure VCSEL présente ainsi des avantages prometteurs pour améliorer les propriétés de ces composants pour une émission dans le moyen infrarouge. Le travail présenté dans ce manuscrit de thèse concerne la conception de miroirs HCG qui répondent...
