Highly efficient electrically–driven single photon sources (SPSs) with a narrow far–field emission pattern suitable for coupling to a single mode fiber are critical components for applications in quantum communication. We address modern concepts of the design of SPSs suitable for such applications: (i) Quantum dot (QD) in a micropillar, where a proper reflectivity balance of top and bottom distributed Bragg reflectors (DBRs) and cavity design allows non–resonant highly directional light source. (ii) Dielectric multilayer structure acting as photon extracting microcavity including a passive cavity design and a deeply etched circular Bragg grating enabling a high efficiency of the light extraction and a narrow far field pattern. The light source is not resonant in wavelength and allows narrow far field distribution at a low series resistance. (iii) Resonant light sources based on broadband high–contrast dielectric DBRs optimized for O–band 1300 nm operation with photon–extraction efficiency above 90% and the coupling efficiency to a single mode fiber of 76%. Resonant tuning of the cavity and QD emission allows Purcell effect–enhancement of the QD photon emission rate.
