摘　　要：利用时域有限差分法和传输矩阵法研究了Fibonacci序列一维准周期光子晶体的能带.结果表明:此种结构的光子晶体在高频范围存在带隙;进一步发现当构成薄膜系的两种材料厚度相等,且膜系的非周期性较强即膜系的级数较高时,光子晶体较容易出现高频带隙.The photonic bands of one-dimension quasi-period photonic crystal with Fibonacci sequence are studied by the finite-difference time-domain method and the transmit matrix method. Our results show that there are photonic band gaps in high frequency for this kind of pbotonic crystal. Moreover when the thickness of the two materials which constitute the films are equal and the films have strong non-periodicity, the photonic crystal with Fibonacci sequence will gain high frequency photonic band gaps.
