Single photon emission at telecom wavelength is observed in InAsP/InP QDs. These dots will be embedded in a metallic subwavelength plasmonic cavity allowing for broadband Purcell factors allowing the engineering of efficient entangled-photon sources.

Photonic crystal based nanolasers have sprung a lot of interest in the latest years due to the high optical confinement of the cavity. High quality factor cavities in conjunction with low electromagnetical volumes, allows to implement a significant enhancement of the spontaneous emission dynamics and hence a preferential funnelling of spontaneously emitted photons into the laser mode. Theoretical...
. We report on a scheme for the creation of time-bin entangled states out of two subsequent single photons. Both photons arrive on the same input port of a beamsplitter and the situation in which the photons leave the beamsplitter on different output ports is post-selected. We derive a full quantum mechanical analysis of such time-bin entanglement for emitters subject to uncorrelated dephasing processes...
