Abstract. Non-classical light will be used in a variety of quantum-enhanced measurements such as imaging and metrology, and quantum measurements and quantum networking. One type of nonclassical light is the single photon source, a light source that provides at most one photon at a time. One of the brightest single photon source is engineered from epitaxial single semiconductor quantum dots in optical cavities. I will discuss how these sources are made and characterized - particularly their nonclassical characteristics. I’ll compare them to other sources, and discuss how they might be used, in particular in quantum photonics.
