Figure | Electrically reconfigurable Gires–Tournois resonator for active colour modulation with addressable reflective monopixel array. a, Schematic illustration of the electrically reconfigurable Gires–Tournois (r-GT) resonator integrated with a conductive polymer. Electrically induced redox reaction of polyaniline enables reversible tuning between insulating and lossy optical states under sub-1-volt operation. The tri-layer structure consists of Au, porous Ge, and PANI, supporting strong light-matter interaction and vivid colour modulation. b, Demonstration of dynamic colour switching using a reflective monopixel array by reproducing “Girl with a Pearl Earring.” This example highlights electrically controlled colour modulation and the capability to fabricate monopixels. c, Addressable reflective monopixel array architecture illustrating pixel-level electrical control and programmable colour patterns. d, Electrically driven colour modulation of the r-GT monopixel under a voltage sweep from -0.2 V to 0.8 V, showing continuous and reversible colour transitions with high chromaticity.
