Selective arrangement of nanoparticles with predetermined nanometer-scale accuracy is crucial to exploit the collective properties of the resulting assemblies, in particular for photonic and electro-optical nano devices. Here, we fabricate topographically patterned templates comprised of laser interference lithography and soft molding to achieve control over position and interparticle distance of the plasmonic building block. We are able to produce 2D square lattice of gold nanoparticles on a centimeter-scale substrate with cost-effective and up-scalable method. Finally, we prove our results using finite-difference time domain simulation and discuss the tunability of the generated surface lattice resonance(SLR), which is correlated to fill factor 0.8.
