| contents | The ability to coherently store and manipulate optical information across multiple degrees of freedom is a central requirement for scalable quantum information processing and multidimensional quantum computing. While polarization- and space-division-multiplexing have substantially increased the capacity of classical optical systems, their extension to coherent and reconfigurable photonic memories remains a key challenge. Here we demonstrate a two-spin-channel-multiplexed photonic memory based on chiral stimulated Brillouin scattering in a chiral photonic crystal fiber. Exploiting the intrinsic preservation of circular polarization in the chiral photonic crystal fiber, left- and right-circularly polarized modes serve as two orthogonal and independent storage channels. Multiple optical data pulses can be selectively or simultaneously stored and retrieved by simply controlling the polarization states of the write-read pulses. The storage time is continuously tunable, and the underlying Brillouin process preserves coherence and channel orthogonality. The result establishes chiral Brillouin scattering as an effective mechanism for spin-channel-multiplexed optoacoustic light storage, providing a robust and scalable platform for multidimensional photonic memories. It also open new opportunities for classic and quantum information processing, reconfigurable quantum networks, and hybrid light-matter interfaces based on coherent acoustic excitations. |
