In this article, recent advances in single photon source technologies based on semiconductor quantum dots are reviewed. After brief overview of progress in quantum dot photonic devices, we address various issues on single photon sources for practical applications, such as operation of the devices at telecommunication wavelength, higher temperature and highly efficient emission. To solve these issues, quantum dots embedded in photonic crystal and GaN-based quantum dots are discussed, demonstrating impact of the quantum dots on single photon source technologies.
