摘要

提出了一种基于二维光子晶体的逻辑与门设计方法。所提出的结构尺寸为18μm×18μm，其中硅棒放置在空气中。线缺陷和点缺陷的产生是为了实现逻辑与门的功能。采用时域有限差分法(FDTD)和平面波展开法(PWE)对该结构进行了32位元的仿真。在1550 nm波长处，横向电(TE)模式在0.735940≤(1/λ)≤1.048702范围内的禁隙为0.31276。设计的与门结构得到了7.62dB的合理对比度(CR)。

A novel design of all optical AND gate based on 2-D photonic crystal

The paper proposes the design of logical AND gate based on two-dimensional photonic crystals. The proposed structure is having the size of 18μm×18μm in which Si rods are placed in air. Line and point defects are created to achieve the functionality of logical AND gate. A 32-bit simulation is carried out using the finite difference time domain (FDTD) and plane wave expansion (PWE) methods to simulate the proposed structure. A forbidden gap of 0.31276 in the range of 0.735940 ≤ (1/λ) ≤ 1.048702 has been obtained for Transverse Electric (TE) mode at 1550 nm wavelength. A reasonable contrast ratio (CR) of 7.62dB is obtained for the designed structure of AND gate.
