Abstract

Controlling spontaneous emission phenomena in semiconductor slabs with a two-dimensional photonic bandgap are discussed. Theoretical simulations predict that the spontaneous emission coupled to the slab modes, which is strongly confined within the slab plane, is inhibited. Simultaneously, the saved energy is redistributed to the spontaneous emission that is coupled to the vertical emission modes. The spontaneous emission control is experimentally demonstrated by measuring time-resolved photoluminescence spectra from GaInAsP quantum-well samples. Our results will open up possibilities for various applications of photonic crystals using spontaneous emission phenomena, including photonics, illuminations, displays, solar cells and even quantum-information systems.
