摘要：

The optical Wannier-Stark ladder in superstructure Bragg grating with a linear chirp was described using a Wannier-function formalism. The solution of coupled mode equations was done in a two-band approximation and an ansatz in which the solutions were given by superposition of Wannier functions. The expansion coefficients were found to be Bessel functions of integer order. Analytical results were found in good agreement with numerical solution of the coupled-mode equations.
