Abstract

We experimentally demonstrate biphoton generation by spontaneous paramet-ric down-conversion in resonant metasurfaces. In our metasurfaces, Mie-type resonances enable over 7 times more efficient biphoton generation compared to an unstructured thin film.

Mie Resonances in the Spectrum of Spontaneous Parametric Down-Conversion

Tomás Santiago‐Cruz, Anna N. Fedotova, Vitaliy Sultanov +6 more

We report on the first-time generation of biphotons via spontaneous parametric down-conversion driven by Mie-type resonances in subwavelength metasurfaces. The measured biphoton spectrum reveals that emission predominantly occurs at the resonant wavelength of the metasurface.

Spontaneous Parametric Down-Conversion from Resonant Metasurfaces

Tomás Santiago‐Cruz, Anna N. Fedotova, Vitaliy Sultanov +7 more

All-dielectric optical metasurfaces are a workhorse in nano-optics due to both their ability to manipulate light in different degrees of freedom and their excellent performance at light frequency conversion. Here, we demonstrate first-time generation of photon pairs via spontaneous parametric-down conversion in lithium niobate quantum optical metasurfaces with electric and magnetic Mie-like resonances at various wavelengths. By engineering the quantum optical metasurface, we tailor the photon-pair spectrum in a controlled way. Within a narrow bandwidth around the resonance, the rate of pair production is enhanced up to two orders of magnitude compared to an unpatterned film of the same thickness and material. These results enable flat-optics sources of entangled photons -- a new promising platform for quantum optics experiments.

Beyond Brightness: Biphoton-State Engineering with Nonlinear Metasurfaces

Alexander S. Solntsev

Nonlinear metasurfaces have been demonstrated as ultrathin photon-pair sources, bringing resonant nanophotonics into a field traditionally dominated by bulk crystals and waveguides. Early experiments established spontaneous parametric down-conversion from nanoantennas and metasurfaces and showed resonant enhancement. Recent experiments and theoretical proposals address a more specific objective: a metasurface that emits the biphoton state required by a particular quantum-optical experiment. Resonant dispersion, mode symmetry, quasi-bound states in the continuum, guided-mode resonances, flatband design, multi-resonance interference, polarisation engineering and tunable emission geometry can shape both the pair-generation probability and the spatial, spectral and polarisation structure of the emitted state. This Perspective examines how these physical parameters determine the joint amplitude and which measurements establish the resulting two-photon state.

Nonlinear metasurfaces for quantum state generation

Thomas Pertsch

We report on experimental and theoretical investi-gations of nonlinear metasurfaces from nanostructured thin films of lithium niobate, and metasurfaces hybridized with transition metal dichalcogenide monolayers. We show that the second-order nonlinear interactions in metasurfaces enable tailorable harmonic frequency generation as well as entangled photon pair sources by spontaneous parametric down-conversion.
