(Color online) Scheme of diffraction-based biosensor based on Bloch surface wave in Kretschmann configuration.
(Color online) Gap map and BSW (solid line) dispersion for TE polarization. The solid and dashed lines are water and ZnSe light line, respectively. The wave vector of the BSW at is indicated with . The arrow corresponds to a momentum contribution for a period one dimensional grating.
(Color online) Calculated diffraction efficiency for a height one dimensional grating of (a) 400 and (b) periods onto a dielectric multilayer (TE polarization) (solid line), a high gold layer (TM polarization) (dashed line), and a ZnSe prism (TM polarization) (dotted line) as a function of the angle of incidence at .
