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 beam and a camera.
