Measured angle-dependent emission enhancement spectra along ΓM (a) and ΓX (b) orientations. Simulated angle-dependent extinction spectra along ΓM (c) and ΓX (d) orientations. (e) Emission spectra of the structured sample and the reference sample in the normal direction. (f) Measured emission enhancement spectrum, measured zero-order transmission spectrum, and simulated zero-order transmission spectrum in the normal direction.
