We investigate second harmonic generation from vertically stacked metal–insulator–metal nanobars arranged in a two-dimensional rectangular array. At specific angles of incidence, the nonlinear emission is maximized due to the near-field enhancement associated with the surface lattice resonance from the periodic arrangement, regardless …

We present a quantum photonic processor featuring 32 modes, with the potential for further scalability. The system demonstrates robustness against extrinsic phase noise, accounting for temperature and acoustic fluctuations. Our initial objective is to tailor this processor for quantum boson sampling (QBS) …

The collective oscillation of free electrons in metals (plasmon) leads to a localized field enhancement at the surface. Structures with periodically arranged metallic nano-particles possess two plasmonic resonances: one from the individual nano-particles (localized surface plasmon resonance, LSPR) and one from the …
