Wavefront Shaping for Optimal Extinction of Focused Light by Individual Nanoscatterers
Laser &Photonics Reviews, EarlyView.Wavefront shaping enables near‐complete optical extinction by nanoscatterers separated from a planar reflector. Time‐reversed emission profiles provide optimal illumination conditions, yielding 70% extinction from a single plasmonic nanoparticle and up to 90% from sub‐wavelength nanoparticle clusters, offering a promising route to efficient in‐ and out‐

Laser &Photonics Reviews, EarlyView.Temporal interfaces are abrupt refractive index changes used in time‐varying optics, but also transitions to nonequilibrium states. This work explores the inelastic scattering of time‐varying light by nonthermal acoustic phonons in the vicinity of temporal interfaces.
