Single nano-particle sensing exploiting crossed polarizers to improve the signal-to-noise ratio

Abstract

Crossed polarized excitation and detection has been used to improve signal-tonoise ratio in an optical nano-particle sensor exploiting guided-resonance-modes in photonic crystal membranes. The sensor can detect particles with a diameter less than 40 nm
