Patent

CA 2370969

A semiconductor device includes an array of long-wavelength VCSELs pumped by a short-wavelength optical pump. The array of long-wavelength VCSELs includes a series of semiconductor recesses, where each semiconductor recess is between two layers of a VCSEL, substantially overlapping the transverse model profile of the VCSEL under operation.

L'invention porte sur un dispositif à semi-conducteur comportant un réseau de lasers VCSEL (à cavité verticale et à émission par la surface) de grande longueur d'onde pompé par une pompe optique de petite longueur d'onde. Ledit réseau comporte une série d'évidements semi-conducteurs placés chacun entre deux couches de VCSEL, et recouvrant sensiblement le profil transversal modèle du VCSEL en fonctionnement.
