High Quality Factor Silicon Membrane Metasurface for Intensity-Based Refractive Index Sensing
We propose a new sensing device based on all-optical nano-objects placed in a suspended periodic array. We demonstrate that the intensity-based sensing mechanism can measure environment refractive index change of the order of <inline-formula><math xmlns="http://www.w3.org/1998/Math/Mat...
