Abstract

The ability to precisely manipulate nanoscale objects and form defined assemblies with extraordinary optical properties has been attracting researchers’ interest for decades. Top-down lithography approaches were the first choice to define sub-wavelength patterns of metasurfaces. Recently, template-based self-assembly methods emerged allowing to deposit chemically synthesized nanoparticle (NP) colloids into tailored traps. Clean-room lithography techniques are required only once—to produce the template master, which can be replicated in an elastomer and used as the NP deposition template. The capillary force deposition ensured nearly 100% yield of tailored single or multi-particle assemblies over cm scales. When the pitch between scattering NPs overlaps the localized surface plasmon band, a high-quality surface lattice resonance (SLR) emerges. We have demonstrated that the SLR can couple to the NP optomechanical oscillations or can be exploited for sensing and nanolasing applications.
