arXiv:2611.10988v1 Announce Type: new Abstract: Telecom-wavelength quantum light sources are essential components for scalable fiber-based quantum networks, where on-demand emission of single photons is required for high secret key rates. Here, we demonstrate the deterministic integration of metal-organic vapor-phase epitaxy (MOVPE)-grown C-band InAs/InP quantum dots into circular Bragg grating resonators. The integrated emitters exhibit a radiative lifetime of $T_1 = (1400 \pm 50)~\mathrm{ps}$ and a spectral linewidth of $\Delta E_{\mathrm{FWHM}} = (41.0 \pm 4.0)~\mu\mathrm{eV}$.
