Generation of single photons carrying spin and orbital angular momenta (SAM OAM) opens enticing perspectives for exploiting multiple degrees freedom high-dimensional quantum systems. However, on-chip generation encoded with single-mode SAM-OAM states has been a major challenge. Here, by using carefully designed anisotropic nanodimers fabricated atop substrate, supporting surface plasmon polariton (SPP) propagation, accurately positioned around emitter (QE), we enable nonradiative QE-SPP...
Ultracompact chip-integrated single-photon sources of collimated beams with polarization-encoded states are crucial for integrated quantum technologies. However, most currently available rely on external bulky optical components to shape the polarization and phase front emitted photon beams. Efficient integration emitters beam shaping encoding functionalities remains so far elusive. Here, ultracompact linearly polarized vortex based emitter-coupled metasurfaces presented, which meticulously...
On-chip manipulation of photon emission from quantum emitters (QEs) is crucial for nanophotonics and advanced optical applications. At the same time, general design strategy still elusive, especially fully exploring degrees freedom multiple channels. Here, vectorial scattering holography (VSH) approach developed recently flexibly designing QE-coupled metasurfaces extended to tempering strength QE into a particular channel. The VSH power demonstrated by designing, fabricating, optically...
Multichannel quantum emission is in high demand for advanced photonic applications such as communications, computing, and cryptography.

We develop the vectorial scattering holography approach, as an inverse design method, with both single-channel and multiple-channel regimes for flexibly designing versatile on-chip QE-coupled metasurfaces. Based on proposed we design, fabricate, characterize quantum light sources of two well-collimated single-photon beams propagating along different off-normal directions orthogonal linear polarizations. Furthermore, experimentally demonstrate generation multichannel emission encoded SAMs...
Entanglement between orbital angular momentum states and polarization of single photons is demonstrated experimentally. This achieved by utilizing metasurfaces for channeling from quantum emitters into highly entangled states.
Hybrid integration of solid-state quantum emitters (QEs) into nanophotonic structures opens enticing perspectives for exploiting multiple degrees freedom single-photon sources on-chip photonic applications. However, the state-of-the-art are mostly limited to two-level states or scalar vortex beams. Direct generation high-dimensional structured single photons remains challenging, being still in its infancy. Here, we propose a general strategy design highly entangled spin-orbital by taking...
