摘要
We propose a one-dimensional (1D) coupled multiple microcavities (MMCs) structure containing negative-index materials. We obtain the photonic Wannier-Stark ladders (WSLs) both in the ordinary and the well-known omnidirectional band gaps by modulating the widths of the cavities. Due to the omnidirectional gaps having novel characteristics compared with the Bragg gaps, it is meaningful to study the WSL that lies in the omnidirectional gap. We study the temporal-spatial evolutions of Gaussian pulses whose central frequencies are in both gaps as passing through the proposed structure. We show for the first time that the electromagnetic Bloch oscillations can occur in such photonic structures containing negative-index materials.
