Fiber-coupled single-photon sources emitting in the near-infrared, O- and C-band are designed for high photon coupling efficiencies. Extensive numerical simulations and optimizations with JCMsuite are performed to maximize the photon extraction and fiber-coupling efficiency of quantum dot single-photon sources based on micro mesas, microlenses, circular Bragg grating cavities, and micropillars.
