摘要：

AlxGa1-xAs　is　a　main　epitaxial　material　of　850-nm　VCSEL.　In　order　to　analyze　lattice　match　and　heat　production,　the　band　gap　of　AlxGa1-xAs　was　built,　using　the　first-principles　calculation　theory.　In　addition,　based　on　thermoelectric　coupling　three-dimensional　(3D)　finite　element　method,　details　on　the　surface　temperature　distributions　of　different　850-nm　VCSEL　arrays　were　analyzed.　Array　spacing　and　array　form　have　an　effect　on　heat　dissipation　of　VCSEL　arrays.　The　diamond　array　with　18　light　emitting　units　shows　the　best　thermal　stability　among　others.
