Optical waveguide spectroscopy

Combination of Surface Plasmon Resonance (SPR) and Optical Waveguide Spectroscopy (OWS) was used for the simultaneous determination of refractive index and film thickness of the hydrogel layers in the Kretschmann configuration [24], The resulting angle scans from the SPR instrument were fit to Fresnel calculations and different layers were represented using a simple box model. A detailed description of this process has been published previously [18]. 

The existence of an evanescent wave was discussed above (cf. Section III), together with PSPs. The optical properties of thicker LBK films can be characterized by the optical waveguide spectroscopy (WGS), and their layered structure can be probed by means of X-ray reflectometry.
