We will describe our group's efforts to use epitaxial InGaAs/GaAs quantum dots as sources of on-demand single photons and indistinguishable single photons. We have demonstrated second order intensity correlation measurements, g2τ, with g2(0) as low as 0.09 at 5 K. g2(0) < 0.5 is demonstrated at temperatures up to 120 K, and nonclassical light is seen to 135 K. We will describe our progress towards microcavity-enhanced emission from single quantum dots, which is necessary for indistinguishable photon emission in this system.
