“…The parabolic confinement and offsets between them are realized by careful designing the structures, which is similar to the experimental design in AlGaAs waveguide arrays [12]. The precise adjustment of each individual waveguide can be realized in nematic liquid crystals, which has a sensitive voltagecontrolled flexibility [26].…”

We have studied the propagation and Zener tunneling of light in the binary parabolic optical waveguide array (BPOWA), which consists of two evanescently coupled dissimilar optical waveguides. Due to Bragg reflections, 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 the field-evolution analysis. The results may have potential applications in optical splitting and waveguiding devices and shed light on the coherent phenomena in optical lattices.
