Based on the exact periodic and soliton solution, the modulation instability (MI) of nonlinear optical lattice with an elliptic function potential has been investigated. The general perturbation coupled equations based on the solutions were obtained, and then were solved by numerical method. It can be found that the perturbation can be affected by the parameters of the optical lattice because the soliton solution depends sensitively on the optical lattice. The modulation depth V affects the amplitude of gain spectrum, while modulation periodic κ affects both the amplitude and fastest growth frequency of gain spectrum.
