Here, we demonstrate a new class of optoelectronic devices on a piece of printing paper using graphene as an electrically reconfigurable optical medium. Our approach relies on electro-modulation of optical properties of multilayer graphene on paper via blocking the interband electronic transitions. The paper based devices yield high optical contrast in the visible spectrum with a fast response. Pattering graphene into multiple pixels, folding paper into three-dimensional shapes or printing colored ink on paper substrates enable us to demonstrate novel optoelectronic devices which cannot be realized with wafer-based techniques.EnglishElectro-opticGraphene photonicsIntercalationOptical propertiesGraphene devicesIntercalationOptical materialsOptical multilayersOptical propertiesOptoelectronic devicesPrintingSurface roughnessElectronic transitionMultilayer grapheneOptical contrastPaper based devicesPaper substratePrinting papersThree-dimensional shapeVisible spectraGrapheneArticle10.1021/acsphotonics.6b00017
