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。
A three-dimensional photonic bandgap (PBG) material was prepared by the micromode method, and a stripped photonic band gap material sample was obtained. The microstructure was an air balloon with a diameter of about 200 nm closely packed with fcc. The macrostructures were rectangular strips with a rectangular cross section of 10 μm and a width of 10 μm and a height of 600 nm. The optical properties of the striped photonic bandgap material were measured by optical fiber laser and the results of SEM were compared with those of conventional photonic bandgap materials prepared by static gravity deposition. A convenient and effective method for preparing patterned photonic bandgap materials.
