Description

The interaction between forward and backward waves in a periodical structure with PT-symmetric potential is investigated. The results demonstrate that the PT-term can change the bandgap of the periodical structure and affect the effective feedback mechanism. The linear solution, reflectivity, dispersion relation, and a generalized analytical solution of this periodical structure are obtained. The influences of the PT-term and detunings on the characteristic of bistability (or multistability) are also discussed. (paper)
