Photon antibunching at high temperature from a single InGaAs/GaAs quantum dot
Richard P. Mirin
We report the observation of photon antibunching from a single, self-assembled InGaAs/GaAs quantum dot at temperatures up to 135 K. The second order intensity correlation, g(2)(0), is measured to be less than 0.260 for temperatures up to 100 K. At 120 K, g(2)(0) increases to about 0.471, which is slightly less than the second-order intensity correlation expected from two independent single emitters. At 135 K, g(2)(0) is 0.667, which still indicates nonclassical light emission that is equivalent to having three independent single emitters.
