| Abstract | We demonstrate the storage and on-demand retrieval of single-photon-level telecom pulses in a fiber cavity. The cavity is formed by fiber Bragg gratings at either end of a single-mode fiber. Photons are mapped into and out of the cavity using quantum frequency conversion driven by intense control pulses. In a first spliced-fiber cavity, we demonstrate storage up to 0.55 μs (11 cavity round trips), with 11.3% ± 0.1% total memory efficiency and a signal-to-noise ratio (SNR) of 12.8 after one round trip. In a second, monolithic cavity, we increase this lifetime to 1.75μs (35 round trips) with a memory efficiency of 12.7% ± 0.2% (SNR of 7.0 ± 0.2) after one round trip. Fiber-based cavities for quantum storage at telecom wavelengths offer a promising route to synchronizing spontaneous-photon-generation events and building scalable quantum networks. |
