In this chapter, we explore and compare structures that employ various combinations of what we classify as four types of light-trapping possibilities: (1) radiated modes, (2) trapped guided and Bloch traveling modes, (3) trapped, spatially localized modes (e.g., Mie modes and localized surface plasmon resonance modes), and (4) hybridizations of these. The structures examined include those having antireflection coatings, random texturing, nanoelement arrays, and plasmonic nanoparticle and nanostructure arrays.
