The　output　characteristics　of　the　vertical　cavity　surface　emitting　laser　(VCSEL)　arrays　are　largely　limited　by　the　thermic　effect　of　electric　resistance.　In　this　paper,　graphene　is　used　as　the　transparent　electrode　of　the　10×10　VCSEL　arrays,　and　the　influence　of　graphene　on　the　device　performance　after　the　introduction　of　the　VCSEL　arrays　with　different　oxide　apertures　is　studied.　The　output　power,　power　conversion　efficiency　and　threshold　current　were　measured.　According　to　the　relationship　between　wavelength　shift　and　power　dissipation,　the　corresponding　change　in　thermal　resistance　is　obtained.　It　was　successfully　proved　that　graphene　improved　the　output　characteristics.　Our　design　provides　a　new　idea　for　alleviating　the　thermal　effect　of　the　VCSEL　arrays.　©　2021　IEEE.
