Preparation and Optical Properties Research of One Dimensional Narrow Band Photonic Crystal
The characteristics of one-dimensional narrow-band photonic crystal including different materials are primarily studied based on experiment. By the means of the electron beam evaporation, a series of narrow band photonic crystal reflectors are prepared in the visible light. The experimental results show that the refractive index ratio can affect inhibition ability of light wave at the corresponding frequency of the photonic crystal. For the same refractive index ratio, the maximum reflectivity is increasing with increasing of periods while band gap is decreasing. For the different refractive index ratio, the smaller the refractive index ratio, the narrower the photonic crystal band gap, the more periods are required to achieve the highest reflectance. Moreover, a hetero structure photonic crystal are also constructed, which can significantly narrow the photonic band gap of photonic crystal, realizing a narrow high reflectivity of the photonic crystal mirror in a shorter period.
