“…In consequence of this effect, excessive electrical fields arise on the surface, which are very sensitive toward changes of the lattice spacing and the dielectric surrounding . Since the first experimental realization in 2008 by the groups of Grigorenko and Barnes, plasmonic SLRs have been shown in a variety of applications such as ultranarrow band absorbers, nonlinear field enhancement, strong coupling to dyes, and engineering of nanolasers …”

Noble metal nanoparticles can absorb incident light very efficiently due to their ability to support localized surface plasmon resonances (LSPRs), collective oscillations of the free electron cloud. LSPRs lead to strong, nanoscale confinement of electromagnetic energy which facilitates applications in many fields including sensing, photonics, or catalysis. In these applications, damping of the LSPR caused by inter‐ and intraband transitions is a limiting factor due to the associated energy losses and line broadening. The losses and broad linewidth can be mitigated by arranging the particles into periodic lattices. Recent advances in particle synthesis, (self‐)assembly, and fabrication techniques allow for the realization of collective coupling effects building on various particle sizes, geometries, and compositions. Beyond assemblies on static substrates, by assembling or printing on mechanically deformable surfaces a modulation of the lattice periodicity is possible. This enables significant alteration and tuning of the optical properties. This progress report focuses on this novel approach for tunable spectroscopic properties with a particular focus on low‐cost and large‐area fabrication techniques for functional plasmonic lattices. The report concludes with a discussion of the perspectives for expanding the mechanotunable colloidal concept to responsive structures and flexible devices.

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...

“…The existence of interference patterns over the whole sample, furthermore, proves the spatial coherence of the observed lasing. Since the K -point of our system corresponds to the crossing of diffractive orders in three directions with 120 • angles between them, the feedback in the lasing action is two dimensional, different from one dimensional DFB lasing [2] in nanoparticle arrays [24,25,28,45]. This is reflected in the non-trivial 2D polarization patterns.…”

Lasing at K Points of a Honeycomb Plasmonic Lattice

We study lasing at the high-symmetry points of the Brillouin zone in a honeycomb plasmonic lattice. We use symmetry arguments to define singlet and doublet modes at the K -points of the reciprocal space. We experimentally demonstrate lasing at the K -points that is based on plasmonic lattice modes and two-dimensional feedback. By comparing polarization properties to T -matrix simulations, we identify the lasing mode as one of the singlets with an energy minimum at the Kpoint enabling feedback. Our results offer prospects for studies of topological lasing in radiatively coupled systems.
