摘要：
Single photon sources operating on-demand at telecom wavelengths are required in fiber-based quantum secure communication technologies. In this work, we demonstrate single photon emission from position-controlled nanowire quantum dots emitting at lambda > 1530 nm. Emission in the C-band is achieved by composition engineering of an InAsxP1-x dot-in-a-rod structure. Using above-band pulsed excitation, we obtain single photon purities of g(( 2 ))( 0 ) = 0.062. These results represent an important step toward the scalable manufacture of high efficiency, high rate single photon emitters in the telecom C-band.
