Experimental Researches On The One-Dimensional Photonic Crystal Microcavity

In experiments, the energy band structures of one-dimensional photonic crystal (1-D PC) is researched. We get the relation between the band gap width and the number of the layers, the dielectric indices contrast, the center wavelength. The microcavity of 1-D PC is made. We study the reflection and transmission characteristics of the microcavity. Experimental results indicate the microcavity of 1-D PC can get a high reflection coefficient and a good stability and substantiality of the membrane layers in air.
