聚合物波导啁啾光栅光衍射的研究

The Difraction Effcicncy of Polymer Optical Waveguide Chirped Grating Prepared by Photobleaching

采用近似方法 ,对于光漂白形成的平面波导啁啾光栅 ,计算了一级衍射光的衍射效率 ,在实验上用光漂白方法制备出 PMMA/ DR1平面波导啁啾光栅 ,测量了光栅一级衍射光的衍射效率 .

With approximated method, the first order diffraction effciency diffraction of waveguide chirped grating was caculated in theory in this paper. The chirped gratings with different photobleaching time on PMMA/DR1 doped polymer waveguied by photobleaching method was prepared and the first order diffraction effciency diffraction of grating was measured in experiment.
