In the context of quantum and nonlinear optics, III-V semiconductors have among the highest optical nonlinearities but cannot be used in conventional phase-matched processes due to the symmetry of their nonlinear susceptibility tensor. However, as phase matching is relaxed when resonant nanoscale resonators are used, III-V semiconductor metasurfaces can be used for harmonic generation, harmonic mixing and parametric down-conversion in ways that have no equivalence when using macroscopic nonlinear media. Some of the results that I’ll present include harmonic generation and generation of entangled photons and complex quantum states using spontaneous parametric down-conversion enabled by quasi bound-states in the continuum resonances.
