Abstract：

It　is　simulated　the　influence　of　Al　component　in　the　distributed　Bragg　reflector　(DBR)　of　vertical　cavity　surface　emitting　lasers　(VCSELs)　on　the　valence　band.　Then　the　devices　with　two　different　structures　were　tested　and　the　results　indicate　that　the　parabolic　gradient　is　effective　to　lower　the　barrier　of　the　valence　band.　Then　the　electrical　current　thermal　effect　of　VCSELs　can　be　improved　and　this　lays　foundations　for　VCSELs　to　continually　work　at　room　temperature.
