Plasmonic lasers offer ultrasmall mode confinement via nanoscale structures, but their reliance on solid-state gain media makes tunability difficult. Yang et al, present a laser based on gold nanoparticle arrays in a microfluidic channel, whose liquid gain media enable dynamic tuning of the lasing wavelength.
