| Sumario: | The demonstration of plasmon-assisted lasing by associating optical gain media with plasmonic nanostructures has led to a new generation of nanophotonic devices with unprecedented performances. However, despite the variety of designs demonstrated so far, the operation of these systems is in most cases limited to a single output wavelength, and some reports on multiline emission refer to mixing single nanolasers with the subsequent limitation in compactness. Here, we show multiline operation from a single plasmon-assisted nonlinear solid-state laser on which a linear chain of Ag nanoparticles is deposited. The system provides lasing at 1.08 μm, which is self-converted to the visible range through different parametric frequency-mixing processes generated at metal-dielectric interfaces. Near infrared and simultaneously green and tunable blue radiation with a subwavelength confinement in the direction perpendicular to the nanoparticle chain, are obtained at room temperature in CW regime. The results demonstrate the possibility of multifunctional operation from a single plasmon-assisted laser and offer new avenues for the development of highly integrable sources of coherent radiation |
