VCSELs exhibit lower threshold current and higher optical bandwidth after applying 1.5 m depth of zinc-induced disordering. With 20-ohm series-resistance reduction, the maximum optical bandwidth can be effectively improved from 19.7 to 22.5 GHz. In addition, the threshold current can be simultaneously reduced from 0.29 to 0.22 mA. ? 2018 GaAs Mantech Incorporated.
