摘要
本文实验证明了一种制作达曼光栅的新方法:在LiNbO3:Fe晶体中利用成像和光折变校应制作光折变达曼光栅.用这种方法制作的达曼光栅除了具有传统达曼光栅的特点,还具有制作实时、简便、可以循环使用的优点.相信在集成光学、光学信息处理中会有重要的应用前景.
We propose a new method to fabricate a photorefractive Dammann grating in this pa- per. Dammann grating is fabricated by photorefractive effect in LiNbO3:Fe crystal using imaging method. The photorefractive Dammann grating has not only the advantage of a conventional Dammmann grating, moreover, the method is real time and very simple, and the crystal can be used recycled. This method can be widely used in optical information processing and integrated optics.
