## Title

- title: Single photon emission from droplet epitaxial quantum dots in the standard
    telecom window around a wavelength of 1.55 μm
  title_type: original
  lang: en

## Description

- description: "We study the luminescence dynamics of telecom wavelength InAs quantum
    dots grown on InP(111)A by droplet epitaxy. The use of the ternary alloy InAlGaAs
    as a barrier material leads to photon emission in the 1.55 μm telecom C-band.
    The luminescence decay is well described in terms\r\nof the theoretical interband
    transition strength without the impact of nonradiative recombination. The intensity
    autocorrelation function shows clear anti-bunching photon statistics. The results
    suggest that our quantum dots are useful for constructing a practical source of
    single photons and\r\nquantum entangled photon pairs."
