摘　　要：利用聚合物PMMA/DR1的三阶非线性光学性质 ,通过两束相干光相互作用形成动态光栅 ,在PMMA/DR1波导上实现了光波导的自衍射 ,测得一级衍射光的衍射效率为 0 .4 %。The dynamic grating based on the third order nonlinear optical properties is formed by interaction of two incident beam in the polymer PMMA/DR1 film. The self-diffraction of light in PMMA/DR1 planar waveguide is studied in this paper. The intensity of the diffracted beams is about 0.4% of the total output.
