摘　　要：对晶格数目对面心立方结构光子晶体带隙的影响进行了详细的实验研究.用不同厚度的材料制作面心立方结构光子晶体,并测量了其禁带的光谱特性.得到了对实际应用有指导作用的规律.一个可实际应用的光子晶体至少应有50个晶格.The effect of number of unit cells of the fcc photonic crystals on the property of the band gaps was investigated experimentally. Fcc photonic crystals with different numbers of cells were fabricated by using recording materials of different thickness in holography. Their transmitted spectra of the band gaps were measured. A guiding rule was given ： a photonic crystal which can be practically used should have 50 unit cells at least.
