“…Exploiting the emerging properties of associating plasmonic nanostructures with dielectric media has become an outstanding tool for concentrating light into small volumes. Chemical and biological sensing, optical trapping and optical tweezers, surface‐enhanced spectroscopies, photovoltaics, fluorescence enhancement of emitting species, and optical circuits are, among others, relevant examples of scientific fields that profit of the extraordinary properties of plasmonic nanoengineered materials.…”

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...

Surface plasmon polaritons in planar graphene superlattices with one-dimensional periodic modulation of the bandgap were studied. The interminiband contribution to the optical conductivity of this system was found by the equation of motion method for two cases: the Fermi level falls within one of the minigaps and the Fermi level is located within one of the minibands. It was shown that the optical conductivity of the system varies significantly in these cases. The spectra of surface plasmon polaritons in the system differs for them.

“…The SPP modes attract an interest from the point of view of communication due to their subwavelength confinement. This property of SPPs can be extremely useful for applications and allows to bring electronics and photonics closer to each other [3,[15][16][17][18][19]. A key active component in the interaction between electronic and photonic subsystems in mixed circuits is a modulator, i.e., the device which converts an electronic signal to an optical signal or vice versa.…”

A combination of computational power provided by modern MOSFET-based devices with light assisted wideband communication at the nanoscale can bring electronic technologies to the next level. Obvious obstacles include a size mismatch between electronic and photonic components as well as a weak light–matter interaction typical for existing devices. Polariton modes can be used to overcome these difficulties at the fundamental level. Here, we review applications of such modes, related to the design and fabrication of electro–optical circuits. The emphasis is made on surface plasmon-polaritons which have already demonstrated their value in many fields of technology. Other possible quasiparticles as well as their hybridization with plasmons are discussed. A quasiparticle-based paradigm in electronics, developed at the microscopic level, can be used in future molecular electronics and quantum computing.
