Spontaneous Emission Properties of Single Emitters in Planar Photonic Crystals

We investigate the quantum-optical interplay of two-dimensional (2D) planar photonic crystals with localized emitters. Due to the spatial variation of the photonic density of states in the photonic crystal unit cell the spontaneous emission properties dependent strongly on the location of the emitter. We infiltrate nanospheres doped with small dye molecules as localized probes into 2D hexagonal Nb
