A Modular Design of Continuously Tunable Full Color Plasmonic Pixels with Broken Rotational Symmetry

Color tuning is a fascinating and indispensable property in various applications. Thus far, variety of reconfigurable approaches have been implemented to achieve color change. However, it still challenge enable continuous over the entire hue range simple, stable, rapid manner without changes configuration material properties. Here, an all-optical continuously tunable plasmonic pixel scheme demonstrated via modular design approach realize polarization-controlled full by breaking intrinsic symmetry unit cell layout. The pixels consist three different types modules corresponding subtractive primary colors. Without changing structural properties or surrounding environment, colors can be precisely tuned across all hues illuminating linearly polarized light with polarization directions. Meanwhile, flexibly customized for processes through appropriate choice component elaborate module layouts. Furthermore, extended achromatic utilization single introduction black module. proposed hold considerable potential function as next-generation integrated liquid-crystal polarizers.
