设计、合成及表征了一种偶氮苯聚合物(PGMAA 20)。研究了该偶氮苯聚合物薄膜中的高密度光学存储和三维微结构,并成功地将20套光栅储存在样品中同一个点上,储存密度是已报道的两倍;用简单的2波混频光路在该材料中刻写出长方格子和六角星型的微结构,在制作多重不同周期不同角度的高密度光栅结构的实验过程中,观察到不同周期光栅的刻写顺序对整个微结构形成的最终结果具有决定性的影响。
An azobenzene polymer (PGMAA 20) was designed, synthesized and characterized. The high-density optical storage and three-dimensional microstructure of the azobenzene polymer film were investigated and 20 sets of gratings were successfully stored at the same spot in the sample with twice the storage density reported. The simple 2-wave Mixing light path in the material to write a rectangular grid and hexagonal star microstructure in the production of multiple different periods of high-density grating at different angles of the experimental process, we observed the grating of different periodic sequence of the entire microstructure The resulting end result has a decisive impact.
