a Transmission spectra of all elements of the fabricated microfilter array. b Distribution of the peak wavelengths of all elements of the fabricated microfilter array. c Typical transmission spectra of microfilter elements: i-ix, the transmission spectra of the microfilters whose photopolymer layer has the thickness of ~240, ~280, ~310, ~330, ~370, ~410, ~430, ~450, and ~480 nm, respectively. d Typical Rabi splitting and peak wavelength shifts in reflection and transmission spectra: (i, ii) the reflection and transmission spectra of a microfilter whose photopolymer layer has a thickness of ~60 nm; (iii, iv) the reflection and transmission spectra of a microfilter whose photopolymer layer has a thickness of ~310 nm.
