a SEM micrograph of the nanohole array realised in a-SiOx:H in a triangular lattice, showing overview and detail. b Experimental reflection spectrum of the nanohole array, highlighting the two main modes. c Cross-section (left) and top view (right) of the energy confinement for TM mode and d TE mode at resonance in the nanohole array. Cross-section of e the electric (left) and magnetic (right) field distribution for the TM mode and f the TE mode on resonance.
