【 摘 要 】

Dual-wavelength second harmonic generation with transverse gradient nested optical superlattice is investigated. The ratio of SHG of two fundamental wavelengths can be controlled by adjusting the position of incident light. This study shows that the efficiency of SHG is related to the temperature and coherent length of the nested structure.
