This chapter briefly overviews the basics of plasmonic crystals and describes some of the important applications for wavelength and polarization management and dynamic control of light using surface plasmon polaritonic crystal (SPPCs). It discusses the basic properties of plasmonic crystals. Effects related to both the lattice, such as bandgap effects and coupling to photons, and the lattice basis are also discussed. The chapter describes the polarization properties of plasmonic crystals and their wavelength and polarization selection applications, emanating from the interaction of light with the crystals' Bloch modes. The chapter also presents several approaches to active plasmonic crystals allowing efficient control of light interacting with the crystals, exploiting the sensitivity of the crystals' eigenmodes to local changes in the dielectric environment. Continuous development of nanofabrication techniques and new requirements for nanophotonic functionalities keeps opening new application fields for such plasmonic nanostructures.
