Biosensing Near the Exceptional Point Based on Resonant Optical Tunneling Effect

Biosensing Near the Exceptional Point Based on Resonant Optical Tunneling Effect

Inspired by exceptional point (EP) sensing in non-Hermitian systems, in this work, a label-free biosensor for detecting low-concentration analytes is proposed, via a special multilayer structure: a resonant optical tunneling resonator. Due to the square root topology near the exceptional point, a re...
