Abstract

The invention relates to the field of surface waves based optical devices particularly tuneable optical filter, optical biosensors and spatial light modulators. An optical sensor and tuneable filter is disclosed based on high contrast periodic structures deposited on a substrate and using a compact reading method for low detection limit using a one dimensionally diverging quasi-monochromatic beamand a camera.

Description

technical field [0001] The present invention relates to the field of surface wave based optical devices, in particular, tunable optical filters, optical biosensors and spatial light modulators. Background technique [0002] Periodic structures exhibit various optical phenomena that are very promising for optical sensing and tunable filtering, as well as other photonic applications. One of the well known periodic structures uses one-, two- or three-dimensional gratings. A good example of such a structure is a metal grating structure, which can excite surface plasmon resonances that are sensitive to the refractive index of the analyte material adjacent to the surface, and thus can be used for biosensing or tunable optical filtering ( Figure 1a ). One of the inventor's patent applications published as WO 2012 / 111001 A2 is based on such ultra-thin metal gratings (<60 nm) which allow excitation of two SP waves, one of which is used as a reference, as in Figure 1b shown. ...
