Hybrid quantum systems, based on semiconductor quantum dots (QDs) and alkali vapors, constitute a recent research field which is attracting a growing attention. An important step for future applications is constituted by the possibility to slow down single photons coming from a QD. This effect has been investigated with photons coming from QDs under different pumping conditions, but always focusing on the absolute achievable delay and not investigating the effect of the photon linewidth. Here we report on a study on the photonic delay for photons with different linewidths. An atomic cell filled with Cs atoms is used as a variable delay line (via vapor temperature variation). Different QDs, which emit photons spectrally on resonance with the atomic transitions, are resonantly pumped and the emitted photons are transmitted through the vapor. QDs with different linewidths bring a different ratio between delayed and non-delayed photons.
