摘要
为使非水溶性红敏光致聚合物材料的全息性能得到改善,采用复合光敏增感、复合引发和复合单体的方法反复对比实验,改善后体系的灵敏度为0.02 cm2/mJ,衍射效率高达83%,计算得到材料的最大折射率调制度为4.1×10-3。实验结果和理论分析表明,利用该材料制作的新型全息光栅具有损耗低、通道宽度窄、衍射效率高等优点,适于制作光通信中的波分复用器及各种光学元件。
The holographic characteristics of water-resisting red-sensitive photopolymer holographic recording material was improved by using compound sensitizer, compound initiator and compound monomer. After improvement, energetic sensitivity of 0. 02 cm^2/mJ and high diffraction efficiency of 83% were obtained. And the refractive index modulation is as high as 4× 10^-3, which implies that the photopolymer has the potential ability of high density holographic storage. Therefore, it is a kind of better holographic recording material. The new style holographic grating fabricated with the material has many merits： low loss, narrow channel width, high diffraction efficiency. According to the experiment results and theoretical analysis, this grating is suitable for wavelength division demultiplexer and other optical elements.
