“…It consists on 1D coupled plasmonic nanostructures (i.e., plasmonic NPs chain) deposited on the surface of a periodically poled LiNbO 3 (PPLN) ferroelectric crystals in which Nd 3+ laser ions are embedded. New features and drastic modifications of the nanoscale lasing operation with respect to the counterpart monolithic lasers are demonstrated . The hybrid plasmonic–ferroelectric material scheme considered here paves the way for the development of solid‐state nanolasers based on the vast list of host‐optically ion combinations for which laser action has been demonstrated.…”

develop novel nanophotonic devices with innovative functions for light generation and control. Indeed, the development of coherent light sources with sub-wavelength confined modes is a flourishing area that can yield a revolution in several fields, including physics, chemistry, materials science, biology, and/or imaging and information technologies. [13][14][15][16] In this review, we discuss the progress on the fabrication and performance features of light sources operating at the nanoscale, which can be attained by the interaction of localized surface plasmons (LSP) with optical gain dielectric media. The optical gain is provided by functional ferroelectric platforms (either by stimulated emission or by nonlinear (NL) frequency conversion processes), which in turn are used as templates for the deposition of metallic arrangements. Two types of sources with sub-diffraction spatial confinement are presented: plasmon-assisted solid-state nanolasers, based on the interaction between metallic nanostructures and optically active rare earth (RE 3+ ) doped ferroelectric crystals, and NL radiation sources based on quadratic frequency mixing mechanisms, that are enhanced by means of LSP resonances.Ferroelectrics are nowadays strong actors in the area of light generation and control. In the context of this report, the relevance of employing ferroelectric crystals as optical functional platforms is multiple. On one hand, the presence of a reversible spontaneous polarization in the ferroelectric phase allows to engineer ferroelectric domain patterns with different photonic functionalities. [17][18][19][20] On the other hand, the noncentrosymmetric crystal structure of ferroelectrics enables the generation of quadratic frequency conversion processes, which makes these systems useful as frequency doublers and optical parametric oscillators. [21,22] Further, the possibility of some ferroelectric crystals to host luminescent trivalent RE 3+ ions, from which laser action can be achieved, is an additional advantage exploited in the context of this work. [23] In fact, some of the materials that will be the subject of discussion in this report constitute true solid-state lasers due to the incorporation of optically active ions such as Nd 3+ or Yb 3+ during the crystal growth. Finally, the presence of surface charges on ferroelectrics is a key factor that allows ferroelectric surfaces to act as templates to assemble different type of nanostructures Coherent light sources providing sub-wavelength confined modes are in ever more demand to face new challenges in a variety of disciplines. Scalability and cost-effective production of these systems are also highly desired. The use of ferroelectrics in functional optical platforms, on which plasmonic arrangements can be formed, is revealed as a simple and powerful method to develop coherent light sources with improved and novel functionalities at the nanoscale. Two types of sources with subdiffraction spatial confinement and improved performances are presented: i) plasmon-assisted solid-sta...

Spatio-temporal Modeling of Lasing Action in Core–Shell Metallic Nanoparticles

Nanoscale laser sources based on single metallic nanoparticles (spasers) have attracted significant interest for their fundamental implications and technological potential. Here we theoretically investigate the spatio-temporal dynamics of lasing action in core–shell metallic nanoparticles that include optically pumped four-level gain media. By using detailed semiclassical simulations based on a time-domain generalization of the finite-element method, we study the evolution of the lasing dynamics when going from a spherical case to an elongated nanorod configuration. Our calculations show that there exists an optimal nanoparticle elongation that exhibits significantly improved lasing threshold and slope efficiency over those obtained for its spherical counterpart. These results are accounted for in terms of a coupled-mode theory analysis of the variation with elongation of the light confinement properties of localized surface plasmons. This work could be of importance for further development of nanoscale light sources based on localized surface plasmon resonances.

Microlasers and waveguidesh ave wide applications in the fields of photonics and optoelectronics. Lanthanide-dopedl uminescent materials featuring large Stokes/ anti-Stokess hift, long excited-state lifetime as well as sharp emission bandwidth are excellent opticalc omponents for photonic applications. In the past few years, great progress has been made in the designa nd fabrication of lanthanidebased waveguidesa nd lasers at the micrometer length scale. Waveguide structures and microcavities can be fabricated from lanthanide-doped amorphous materials through top-down process. Alternatively,l anthanide-doped organic compounds featuring large absorption cross-section can self-assemble into low-dimensional structures of well-defined size and morphology.I nr ecent years, lanthanide-doped crystalline structures displaying highly tunable excitation and emission properties have emergeda sp romising waveguide and lasing materials,w hichs ubstantially extends the range of lasing wavelength. In this minireview, we discussr ecent advances in lanthanide-based luminescentm aterials that are designed for waveguide and lasing applications.W ea lso attempt to highlight challenging problems of these materials that obstacle further development of this field.[a] Dr.
