Plasmon‐Induced Disorder Engineering for Robust Optical Sensors

Optical metasurfaces address a plethora of applications in planar optics, as they enable precise control the phase, amplitude, and polarization light at nanoscale interaction lengths. However, their implementation requires surface nanostructuring, based on complex design fabrication methods. In addition, exploiting narrow spectral features, e.g., for sensing, is accompanied by high demands terms post-process alignments probing light—impractical compact optical systems. Here, realization plasmonic metasurfaces, silver nanoparticles (AgNPs) using solution-based growth method, demonstrated. The particle mediated localized plasmon resonances. resulting nanostructures are directly applicable self-optimized systems, procedures allow use common—photonic plasmonic—platforms.
