A laser diode for integrated photon pair generation at telecom wavelength

A fully integrated photon pair source is a key element to achieve quantum optics circuitry on chip. Such a source could be easily combined with promising nanophotonic technologies such as plasmonic waveguides [1] or multipath integrated optical interferometer [2]. As mature technologies, semiconductors exhibit a huge potential in terms of integration (electrical pumping, advanced nanostructure design).
