Summary: The authors demonstrate the detection and control of single Erbium ions emission using electro-optically active photonic crystal cavities made from thin-film lithium niobate. Purcell-enhanced emission in optical cavities is utilized to probe single ions with low emission rates, and dynamic control of emission rate is achieved through electro-optic tuning of resonance frequency. These results provide promising opportunities for controllable single-photon sources and efficient spin-photon interfaces.

Summary: This study proposes a novel thin-film lithium niobate parametric down-conversion single-photon source based on mode dispersion phase matching theory, which differs from traditional periodic polarization quasi-phase matching technology. Instead of matching the pump and parametric light in their fundamental modes, this method matches the pump light's higher-order mode with the parametric light's fundamental mode using an asymmetric directional coupler. This innovative solution is expected to replace traditional quasi-phase matching single-photon sources and further promote optical quantum information research based on thin-film lithium niobate chips.

Summary: This paper proposes and models an ultra-broadband TM-pass waveguide polarizer based on a thin-film LiNbO3-on-insulator waveguide and sub-wavelength grating (SWG) metamaterials. The device consists of an SWG as a polarization filter, and two coupling regions to reduce mode mismatch loss. Simulation results show that the polarizer can achieve an ultra-large bandwidth of -415 nm (1.26-1.675 mu m) with low insertion loss (<1.1 dB) and high extinction ratio (>29.4 dB). Additionally, the proposed polarizer can tolerate deviations in the width and thickness of the nano-stripes by 5 nm. This ultra-broadband device may have applications in high-capacity optical communication systems, and it is the first of its kind proposed on the lithium-niobate-on-insulator platform, to the best of our knowledge.

Summary: The use of a nonlinear metasurface and a thin film allows for the flexible manipulation of complex polarization states of photon pairs. It is found that the orientation of the metagratings can shape the polarization states of the photon pairs.

Summary: We propose and demonstrate the preparation of desired two-photon polarization states using a nonlinear metasurface incorporating multiplexed silica metagratings on a lithium niobate film. The two-photon polarization states can be shaped by adjusting the metagrating orientation, and by combining multiple metagratings, arbitrary polarization-entangled qutrit states can be generated. This enables the miniaturization of optically controlled quantum devices using ultrathin metasurfaces as polarization-entangled photon sources.
