Using experimental and simulation methods, we demonstrate that structures consisting of two-dimensional arrays of closely-packed flat metallic nanodisks can support optically active collective resonances associated with the dark edge modes. Our results show that such resonances appear as the refractive index of the superstrate increases, generating a relatively sharp peak with weak sensitivity to the variations of the environment. Using a consecutive multilayer deposition of Si on the top of the arrays we map the development of such a resonance via multi-step red shifting of the Rayleigh anomaly wavelength. The results show that when the Rayleigh wavelength is sufficiently close to the subradiant quadrupole edge modes of the nanodisks, a linearly polarized light can excite such modes, resulting in optically active collective resonance.
