We analytically and numerically study coupling mechanisms between 1D photonic crystal (PhC) and 2D array of plasmonic nanoparticles (NPs) embedded in its defect layer. We introduce general formalism to explain and predict the emergence of PhC-mediated Wood–Rayleigh anomalies, which spectral positions agree well with the results of exact simulations with Finite-Difference Time-Domain (FDTD) method. Electromagnetic coupling between localized surface plasmon resonance (LSPR) and PhC-mediated Wood–Rayleigh anomalies makes it possible to efficiently tailor PhC modes. The understanding of coupling mechanisms in such hybrid system paves a way for optimal design of sensors, light absorbers, modulators and other types of modern photonic devices with controllable optical properties. © 2018 Elsevier Ltd
