“…To cite some examples, the enhancement of the electromagnetic field at metal–ferroelectric interfaces has been exploited for boosting the Raman scattering, the spontaneous emission of laser ions, or even the radiation produced by NL processes at the metal–dielectric interfaces . Further, it can also give rise to plasmon‐assisted nanolasers displaying sub‐wavelength confined modes with potential applications in ultrahigh density data storage, sensing, or biological applications …”

“…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...

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.

“…Also, by operating at NIR region with relatively low metal losses, metal‐cladded 3D‐confined subdiffraction‐limit plasmonic nanolasers have been demonstrated, in which the cladding metals support TM cavity modes and behave more like perfect reflecting mirrors . In addition, a new category of plasmon‐assisted nanolasers are also demonstrated recently, using plasmonic effect to enhance the pumping intensity or reduce the output mode size . However, the confinement of the lasing modes in these systems are usually compromised, and we will not go into details here.…”

and techniques have been proposed and/ or developed. Here we focus on a newly emerging area-plasmonic nanolaser that pursuing extremely smaller cavity size in one or more dimensions, and consequently extreme lasing conditions, by using a plasmonic cavity with feature size possibly far below the diffraction limit of light.The miniaturization of a laser can be traced back to the early age of the laser, when compact semiconductor structures were introduced. In particular, the introduction of semiconductors as the gain media in 1962, [11,12] followed by a series of elaborately engineered structures from heterostructure, [13] quantum well, [14] vertical-cavity surface-emitting laser (VCSEL), [15,16] microdisk, [17][18][19] photonic crystal, [20][21][22] quantum dot [23,24] to nanowire (NW) [25][26][27] have made great success in shrinking a laser from bulk scale to wavelength level using reduced cavity sizes. [28] For example, to date, typical commercial edgeemitting quantum well laser diodes have dimensions of several micrometers in width and hundreds of micrometers in length, and a single quantum dot can lase in a photonic crystal cavity with overall dimension of merely 0.7(λ/n) 3 , where λ is the vacuum wavelength and n the refractive index of the dielectric. [29] With optimized geometry and material for cavity design, lower structural dimension is expected. However, in a dielectric cavity with limited refractive index n, the cavity size is intrinsically restricted by optical diffraction limit that sets an ultimate limit λ/2n for both cavity length and mode size in all three dimensions.An effective step to shrink a cavity beyond the diffraction limit is converting light into surface plasmon polaritons (SPPs) in nanostructuralized metals, which is a kind of collective oscillation of quasi free electrons on the interface of a metal and a dielectric. [30] While SPP is featured with ultrahigh optical confinement and ultrafast relaxation process as shown in Figure 1a, [31] it is inevitably accompanied by ultrahigh energy dissipation (i.e., Ohmic loss), leading to a mutual balance between the mode size and the optical loss in either a nanowaveguide or a nanocavity as shown in Figure 1b. [32] For example, the transverse mode area of SPP mode on an Ag nanowire with diameter of 100 nm can be as small as 0.01 µm 2 but also exhibits a propagation loss larger than 200 dB mm −1 . Despite of the high loss coefficient of plasmonic resonance at optical frequency, a properly designed nanoplasmonic cavity coupled with a gain medium is possible to lase with miniature cavity length.Owing to their ultrahigh optical confinement, plasmonic nanolasers with cavity sizes beyond the diffraction limit of light, are attracting increasing attention for pursuing extreme lasing conditions on nanoscale including ultracompact cavity mode, ultrafast lasing modulation, significantly enhanced light-matter interaction, and Purcell effect. In this review, the recent progress on plasmonic nanolasers from both theoretical and experimental aspects is intro...
