我们报告的制作布拉格光栅的肋型波导的先前UV固化的无机-有机Ormocer混合聚合物通过应用干涉相位掩模技术结合深紫外激光辐射。的制作过程，以及施加的激光能量密度和布拉格光栅的长度上的布拉格光栅的透射和反射光谱的特性的影响进行了讨论，并进行了比较，数值模拟和计算。根据所施加的激光能量密度和所选择的光栅长度，波导布拉格光栅具有高达98%的强反射率和低至120 pm的窄带宽已经实现。(C)2016美国光学学会
We report on the fabrication of Bragg gratings within rib-type waveguides of previously UV-cured inorganic-organic Ormocer hybrid polymers by applying the interferometric phase mask technique in conjunction with deep-UV laser radiation. The fabrication process as well as the influence of the applied laser fluence and the length of the Bragg grating on the characteristics of the Bragg grating's transmission and reflection spectra are discussed and compared to numerical simulations and calculations. Depending on the applied laser fluence and the chosen grating length, waveguide Bragg gratings with strong reflectivities of up to 98% and narrow bandwidths of down to 120 pm have been achieved.
