- Abstract summary: We demonstrate a highly efficient fiber-interfacing photonic device that directly launches single photons from quantum dots into a standard FC/PC-connectorized single-mode fiber.
Our approach realizes a plug-and-play single-photon device that does not require any optical alignment and thus guarantees long-term stability.

- Abstract: Incorporating solid-state quantum emitters into optical fiber networks
enables the long-distance transmission of quantum information and the remote
connection of distributed quantum nodes. However, interfacing quantum emitters
with fiber optics encounters several challenges, including low coupling
efficiency and stability. Here, we demonstrate a highly efficient
fiber-interfacing photonic device that directly launches single photons from
quantum dots into a standard FC/PC-connectorized single-mode fiber (SMF28).
Optimally designed photonic structures based on hole gratings produce an
ultra-narrow directional beam that matches the small numerical aperture of a
single-mode fiber. A pick-and-place technique selectively integrates a single
miniaturized device into the core of the fiber. Our approach realizes a
plug-and-play single-photon device that does not require any optical alignment
and thus guarantees long-term stability. The results thus represent a major
step toward practical and reliable quantum lights across a fiber network.
