Abstract
At least four groups have demonstrated GeSn direct bandgap material and shown cryogenic temperature lasers under optical pumping. With up to 16% of Sn, our lasers operate up to 180K and lase up to wavelengths of 3.1 um. We will describe our efforts to reduce the threshold, increase the operating temperature, and evolve towards electrical pumping in these lasers.Thes efforts involve improvements of epi growth, electrical passivation, doping, heterostructures, strain control...
