Abstract
Room temperature direct gap electroluminescence (EL) from a Ge/Si0.15Ge0.85 MQW waveguide was experimentally studied. The dependence of the EL intensity on the injection current and temperature was measured. The direct gap EL from Ge/SiGe MQWs was shown to be transverse-electric (TE) polarized, confirming that the EL originates from recombination with a HH state.
