摘要We have studied the propagation and Zener tunneling of light in a binary parabolic optical waveguide array (BPOWA), which consists of two evanescently coupled dissimilar optical waveguides. Because of Bragg reflections, the BPOWA attains two minibands separated by a minigap at the zone boundary. Various coherent superpositions of optical oscillations and Zener tunneling occur for different parameters on the phase diagram. In particular, Bloch-Zener oscillation and a different type of Bloch-dipole-Zener oscillation are obtained by field-evolution analysis. The results may have potential applications in optical splitting and waveguiding devices and may shed light on the coherent phenomena in optical lattices. (c) 2011 Optical Society of America
