a Rabi splitting and opposing wavelength shift phenomena: (i–iii) the transmission spectra of the microfilters with different sizes of AgNPs when the thickness of the photopolymer layer(t) is 250, 320, and 400 nm, respectively. b Wavelength shifts caused by the change of photopolymer layer thickness: (i, ii) the transmission spectra of the microfilters with different thicknesses of the photopolymer layer when the diameter of AgNPs(d) is 10 and 8 nm, respectively. c Anti-crossing phenomenon, based on the peak wavelength data from (b(ii)). d Modulation effect of AgNP size on the transmission spectra of total microfilter structure: (i–iii) the transmission spectra of the microfilters whose photopolymer layer has the thickness of 200, 300, and 400 nm, respectively. e Modulation effect of polymer layer thickness on the transmission spectra of total microfilter structure: (i–iii) the transmission spectra of the microfilters with 0, 10, and 20 nm AgNP diameters, respectively.
