Lossy Mode Resonance Sensors Based on Anisotropic Few-Layer Black Phosphorus.

ABSTRACT: Lossy mode resonance (LMR) sensors offer a promising avenue to surpass the constraints of conventional surface plasmon resonance (SPR) sensors by delivering enhanced label-free detection capabilities. A notable edge of LMR over SPR is its excitation potential by both transverse electric (TE) and transverse magnetic (TM) polarized light. Yet this merit remains underexplored due to challenges to achieving high sensing performance under both TM and TE polarization within a singular LMR model. This study introduces a theoretical model for an LMR prism refractive index sensor based on a MgF₂-few layer black phosphorus-MgF₂ configuration, which can achieve angular sensitivity nearing 90° refractive index unit^-1 (RIU^-1) for both polarizations.
