“…In case the component of the laser electric field is enough to initiate the surface modification, the orientation of periodic nanostructures follows the orientation of artifi-cial seed rather than the laser polarization (Figure S12, Supporting Information). [52] If the crossing angle ϕ between seed orientation and laser polarization is too small, one can further employ circular polarization (Figure 4f) to obtain curved nanogratings. We expect that more complicated nanotexturing can be achieved by rationally designed seeds.…”

“…Afterward, the utilization of more complicated micro/nanostructures to influence the LIPSS has been investigated, including metallic and semiconductor nanoparticles, [49] gold micro-flakes, [50,51] and step edges. [52] These works mainly focused on the mechanisms of LIPSS, such as the contribution of Fresnel diffraction and SPPs, and the roles of plasmonic and Mie scattering fields. Their feasibility for largescale high-quality manufacturing has not been deeply investigated.…”

Surface plasmon polaritons (SPPs), being localized at nanoscale and coherent with driving field, are attractive for large‐scale surface nanopatterning. Under femtosecond laser irradiation, the interference between incident light and excited SPPs is efficient to produce periodic nanostructures. However, it generally relies on self‐initiated seeds, which are random and uncontrollable, leading to irregular patterns. Here, controllable laser plasmonic nanopatterning is experimentally illustrated in terms of artificial seeds that are pre‐structured by laser direct writing. The approach is demonstrated on bilayer ultrathin films, consisting of a 50‐nm‐silicon coating on a 100‐nm‐platinum (Pt) or silver (Ag) film. The artificial seeds are in form of silicon oxide. The Pt is utilized to support SPPs, and the nanopatterning occurs in Si film via laser‐induced periodic oxidation. The underlying mechanisms of this approach are numerically investigated and experimentally verified. The typical problems, such as bifurcation, distortion, wavy, and poor splicing are all solved by the artificial seeds. Therefore, large‐scale nanogratings with extremely high uniformity are readily produced. Furthermore, manipulating the orientation of periodic nanostructures by the artificial seeds associated with controlled light polarization is illustrated. When using circularly polarized lasers, the artificial seeds can facilitate a diverse range of periodic patterns with arbitrary while controllable orientation.

“…For metals, this modulation results mainly from an interference between the incident light and surface scattered light assisted by surface plasmon polariton (SPP) excitation. [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34] In principle, the IED can be partly calculated with analytical expressions [21,27,35] or with numerical approaches such as finite-difference time-domain (FDTD) simulations. [20,[22][23][24]36] A change in surface topography as machining progresses is expected to affect the IED; [22,30,31] this change is referred to as inter-pulse feedback.…”
