Propagation behavior of incoherent beams in one-dimensional photonic crystals

摘要

The propagation properties of Gaussian Schell-model spatially incoherent beams through a one-dimensional photonic crystal (1DPC) are investigated. The dynamical evolution of incoherent beams in 1DPC and the Goos-Hanchen lateral shift of the transmitted beams are obtained. The mutual effects of coherence and bandgap of the PC on the evolution of incoherent beams are analyzed. The incidence angle of the incoherent beam also has an influence on the incoherent electric field and the lateral shift.
