Abstract

For the enhancement of light matter interactions plasmon resonances have been crucial. However, their low quality factors have limited their application in areas requiring high spectral selectivity. A new approach involving the design and 3D laser nanoprinting of plasmonic nanofin metasurfaces has been demonstrated to support bound states in the continuum up to the 4th order. The out-of-plane symmetry of the nanofins can be fine-tuned by altering the triangle angle, enabling control over the ratio of radiative to intrinsic losses. Pixelated molecular sensing in the Mid-IR unveiled the importance of precise coupling tailoring in order to create high performance sensors.
