Abstract

Abstract: 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 sub‐diffraction spatial confinement and improved performances are presented: i) plasmon‐assisted solid‐state nanolasers based on the interaction between metallic nanostructures and optically active rare earth doped ferroelectric crystals and ii) nonlinear radiation sources based on quadratic frequency mixing processes that are enhanced by means of localized surface plasmon (LSP) resonances. The mechanisms responsible for the intensification of the radiation–matter interaction processes by LSP resonances are discussed in each case. The challenges, potential applications, and future perspectives of the field are highlighted. Abstract : Hybrid plasmonic–ferroelectric materials are excellent candidates for the development of functional coherent light sources at the nanoscale. Two types of sources with subdiffraction spatial confinement are reviewed: plasmon‐assisted solid‐state nanolasers comprising metallic nanostructures and optically active rare earth (RE 3+ )‐doped ferroelectric crystals, and plasmon‐enhanced nonlinear radiation sources based on frequency‐mixing mechanisms.
