Nanolasing in Self-Assembled Metasurfaces
Paper in proceeding, 2023

Plasmonic surface lattice resonance-based (SLR) nanolasers are attractive because of their small mode volumes and footprint, ultrafast dynamics, and good beam directionality.1 Underlying plasmonic nanocavities are usually produced by conventional lithography processes. We have developed a deposition method to arrange monodisperse, colloidal nanoparticles onto macroscopic, patterned substrates, otherwise metasurfaces, with a high assembly yield.2,3 Furthermore, we have shown that the SLR can drive the lasing modes from the fluorescence spectra of the organic dye when pumped with ultra-short laser pulses.
