With this work, we report on the quantum storage of a heralded frequency-multiplexed single photon in an integrated laser-written rare-earth doped waveguide.  In particular, a frequency-multimode photon is stored in a praseodymium-doped waveguide using the atomic frequency comb (AFC) scheme and we demonstrate that the storage preserves the nonclassical properties of the single photon.
