We have demonstrated AlGaAs/GaAs VCSELs optimized for operation in the cryogenic region from 150K to 10K, with superior DC lasing characteristics including a high output power, low and nearly constant threshold current, low operating voltage, a slope efficiency of ~100%, and a 11GHz modulation bandwidth that is limited by parasitics
