摘要

提出了一种基于二维光子晶体的全光或门的设计方法。所提出的结构由放置在空气中的Si棒组成，其尺寸为15μm×18μm，具有点和线缺陷。采用时域有限差分法(FDTD)和平面波展开法(PWE)对1550 nm波长处的结构进行了模拟。横磁(TM)模式在0.316417≤(1/λ)≤0.358938范围内的禁隙为0.0425。本设计获得的对比度为10dB，为高速光通信器件的设计提供了基础器件。

Design of all optical logical OR gate based on 2-D photonic crystal

The paper presents the design of all-optical OR gate based on the 2-D photonic crystal. The proposed structure consists of Si rod placed in the air of having the size 15μm×18μm with point and line defects. The Finite difference time domain (FDTD) and plane wave expansion (PWE) methods are used for simulating the structure at 1550 nm wavelength. The forbidden gap of 0.0425 in the range of 0.316417 ≤ (1/λ) ≤ 0.358938 has been obtained for Transverse Magnetic (TM) mode. The obtained contrast ratio is 10dB for this design which makes it advantageous as a basic component for the design of high-speed optical communication devices.
