From: Scalable nanopatterning of organic light-emitting diodes beyond the diffraction limit
a-d Experimental PL BFP images and \({{\rm{S}}}_{1}/{{\rm{S}}}_{0}\) polarization maps of electroluminescent metasurfaces based on 1D arrays of 100 nm-wide nanorod pixels. The nanorod arrays have periodicities of 250 nm (a), 300 nm (b), 350 nm (c) and 400 nm (d). e-h, Corresponding angle-dependent PL spectra along the \({k}_{y}\) direction, with the polarizer parallel (p-pol.) and perpendicular (s-pol) to the spectrometer slit.
