| 摘 要： | 采用微模法制备了三维光子能降(PBG,photonic band gap)材料,得到了TiO_2为骨架的条状光子能隙材料样品。其微观结构为fcc密堆积的直径200nm左右的空气球,宏观结构为彼此相距10μm的横截面为矩形的长条,矩形宽度为10μm,高度600nm。用光纤导入激光的方法对条状结构光子能隙材料的光学性质进行了测量,结合SEM的测量结果并与通常的静置重力堆积制备的光子能隙材料样品进行了比较,证实了这是一种方便、有效的制备具有图形的光子能隙材料的方法。

| Abstract: | A kind of 3-dimensional photonic band gap (PEG) material which is TiO2 matrix in strips shape is fabricated by using micromolding method. The periodic ridge strips, 10 μm in spacing, are composed of fee packed 200 nm-diameter air spheres, the cross-section of the strip is 10 μm wide and 600 ran in depth, which was observed by SEM measurement. Laser light was coupled into strips by optical fiber to characterize the optical properties of the PBG material. The observed optical band-gap structure is same as that of the PBG material obtained by conventional gravity-deposit-method. And so the above approach is a convenient, efficient way to fabricate PBG materials with patterns. |
