摘要: Publisher Summary This chapter presents a theoretical description for emission from one-dimensional planar microcavity, where the light is generated in thin layer. It also discusses characteristics of metallic and dielectric mirrors, interference effects near single mirror, related to Fabry–Perot modes. The discussed use microcavity practical electroluminescent (EL) devices: inorganic EL, organic EL devices, light-emitting diodes. Inorganic film devices have an optical thickness several wavelengths, therefore enhancement very sensitive small variations angle wavelength. Thus, microcavities limited applications phosphor material has narrow spectral line, which collected solid angle. Light-emitting diodes based on quantum wells generate layer can profit wide-angle effect, if well placed antinode cavity.
