Abstract
There will be overviewed our recent results on engineering the electronic and optical properties of InGaAs/GaAs and InAs/InP quantum dots suitable for single photon emitters in the 1.3-1.55 µm range. There will be discussed the issues of single photon emission purity and its temperature stability in relation to the underlying physics of the confined excitonic complexes and in view of fundamental limitations of the fabrication technologies, as well as engineering the photonic confinement for controlling the emission rates, emission polarization and light collection efficiency. Eventually, there will described a solution for constructing stand-alone, cryogenic-free fiber-coupled sources operating at telecom wavelengths.
