Frequency Hopping (FH) systems are increasingly popular in contemporary wireless communications, especially in military communications and electronic confrontations. The key performance of FH systems includes robustness, continuation, and resilience. To measure these factors, additional interference is introduced into FH systems, and a large number of algorithms and schemes have been proposed to maximize...
We present the efficient generation of coherent single photons based on quantum dots in micropillars. We utilize a scalable lithography scheme leading to quantum dot-micropillar devices with 74% extraction efficiency. Via pulsed strict resonant pumping, we show an indistinguishability of consecutively emitted photons up to 98.5%.
