Abstract

Symmetry-protected bound states in the continuum (BICs) combines high-quality factors (q-factors) with a large spectral tunability, offering an ideal platform for optical sensing. We present a plasmonic nanofin metasurface harnessing the out-of-plane symmetry breaking in parameter space by tuning the opening angle of 3D laser nanoprinted polymer triangles coated with gold. The plasmonic nature of the out-of-plane symmetry-protected BICs enables high surface field enhancement together with high q-factors, which have been utilised for refractive index and pixelated molecular sensing.
