We demonstrate electrically switchable nanoantennas and metasurfaces from metallic polymers. Such nanoantennas show well-pronounced plasmonic resonances and can be electrically switched fully off and back on by applying CMOS compatible voltages of ±1V. Operation speed is as fast as 30 Hz. Utilizing this concept, we realize, on the one hand, an electrically switchable metallic polymer metasurface for ultra-high-contrast active beam switching. On the other hand, we show an electro-active metaobjective comprising two metalenses-on-demand. By using gel electrolytes, our metadevices can be integrated into state-of-the-art on-chip electro-optic components.
