摘　　要：本文基于时域有限差分(FDTD)法,模拟了由氧化铝圆柱棒构成的二维光子晶体和具有线缺陷的二维光子晶体波导的传输特性。结果表明,该光子晶体在红外波段(1.35-2.12um)上存在光子带隙,缺陷态在1.5-1.6um的波段。光子晶体的这一特性可以用来进一步发展红外光波导。The finite-difference time-domain(FDTD)method was used to calculate transmission characteristic of two-dimensional photonic crystal and two-dimensional photonic crystal waveguide with line-defect,which has periodic Al2O3 cylinder array structure.Numerical simulation results showed that PBG of photonic crystal existed in the range 1.35-2.12um(infrared waveband)and defect state existed in the range 1.5-1.6um,and it may be used to develop infrared guide.
