Room temperature spontaneous emission in five‐micron‐long Fabry–Pérot vertical cavities

摘要: Five‐micron long AlGaAs/GaAs Fabry–Perot vertical cavities with thin GaAs active regions of two different thicknesses are analyzed both theoretically and experimentally in terms their optical transmission characteristics, spontaneous radiation patterns, spectral emission characteristics. The effects on the precise placement region also thickness this region, as compared to emitted wavelength, demonstrated. measured results theoretical calculations which based first‐order perturbation field theory presented an earlier publication. Good agreement is found comparison between predictions experimental results, indicates controllable these cavities.
