Efficient optical modeling of spontaneous emission in a cylindrically layered nanostructure.
We present an efficient optical model to study spontaneous emission in a cylindrically layered nanostructure. The total emission power of an emitter in the nanostructure is efficiently calculated. A formula is derived to calculate the lateral-surface emission power. As examples of practical interest, spontaneous emission properties, including radiative transition rate of the emitter, the assignment of the emission to lateral-surface emission and waveguided emission, are comprehensively studied at the first time for an isolated ZnO nanowire and a ZnO/SiO(2) nanocable.
