Polarization‐Sensitive Subwavelength Nanopixel for On‐Off and Color Switchable Color Printing (Advanced Optical Materials 11/2025)

Nanopixel for Color Conversion and On-Off Switching In article 2402032, Kyujung Kim and co-workers present a polarization-sensitive dual nanodisk nanopixel, enabling precise color modulation and on-off switching. By adjusting plasmonic coupling through dielectric gaps and the polarization direction, it achieves significant control over wavelength shifts and light intensity, paving the way for innovative applications in optical devices, sensors, and data encryption.
