摘　　要：采用一维变折射率光子晶体设计了光学二极管,该结构中介质A和B的折射率随空间位置线性变化.通过计算在一定条件下光子晶体的正向与反向入射的透射率和电场分布,得出正向入射光可以通过该结构光子晶体,而反向入射光不能通过该结构光子晶体,此结构光子晶体可以制成光学二极管.The optical diodes was designed by one-dimensional function photonic crystals(FPCs),which the refractive indexes of media A and B were the functions of space coordinate.By calculation the transmissivity and electric field distribution,the positive incident light could pass through the function photonic crystals,but the negative incident light was not pass through it,the function photonic crystals(FPCs)could be made into optical diodes.
