We demonstrated a room-temperature continuous-wave operation of the single-mode green and blue VCSELs with epitaxially grown AlInN/GaN DBRs. Our blue VCSELs show the highest wall-plug efficiency of 13.6% and stable CW operation. Our green VCSELs also provide the highest optical output power exceeding 1.5 mW and wall-plug efficiency of 3.7%.
