We demonstrate that the coherence of the emitted single photons is tailored by the resonant excitation with a spectral linewidth below the radiative limit. Our ultra-coherent source opens the way for integrated quantum devices dedicated to the generation of single photons with high degrees of indistinguishability. %G English %2 https://hal.science/hal-00659992/document %2 https://hal.science/hal-00659992/file/APL_Nguyen.pdf %L hal-00659992 %U https://hal.science/hal-00659992 %~ UNIV-PARIS7 %~ ENS-PARIS %~ UPMC %~ LPA %~ CNRS %~ LPA-OPT %~ L2C %~ PSL %~ UPMC_POLE_2 %~ MIPS %~ UNIV-MONTPELLIER %~ SORBONNE-UNIVERSITE %~ SU-SCIENCES %~ UNIV-PARIS %~ ENS-PSL %~ SU-TI %~ ALLIANCE-SU %~ UM-2015-2021
