Biphoton interference from spectrally overlapping resonances in nonlinear metasurfaces
Two-photon interference between two photon pairs, or biphotons, requires the interfering biphotons to be indistinguishable. Previously, researchers have demonstrated this by coherently pumping two identical but separate nonlinear materials or using multipass interferometric setups. In contrast, we demonstrate two-photon interference of biphotons simultaneously emitted by two overlapping resonances in the same nonlinear source—a nonlinear metasurface.
