Abstract
In the field of photonic and opto-electronic components, an optical filter comprises a plurality of semi-conducting nano-/microparticles, exhibiting properties of electromagnetic resonance in the optical and near-infrared domain, arranged on a plane, characterized in that it furthermore comprises a layer with electrically adjustable optical index disposed on the surface formed by said nano-/microparticles and said plane; a first electrically insulating layer disposed on said layer with electrically adjustable optical index and an electrode disposed on said first electrically insulating layer.
