    Abstract

    Data are presented showing that lithographic vertical-cavity surface-emitting lasers (VCSELs) produce minimal junction temperature rise compared to oxide VCSELs. Eliminating the thermal block caused by internal oxides combined with improved mirror materials reduces the junction temperature. The elimination of internal oxide, lower junction temperature and reduced internal strain promise increased reliability in the new VCSELs. Power conversion efficiencies in excess of similar to 50% are reported, even for very small lithographic VCSELs.
