摘要

本文提出了一种基于光子晶体的全光全减光器结构。该结构包括六个非线性谐振环，用于将入射光波传输到输出端口。对非线性杆采用不同的半径，使得在不同的光强量下进行滴注操作成为可能。非线性棒由掺杂玻璃制成，光学克尔系数为10-15 m2/W。为了计算整个结构的光波分量，采用时域有限差分法。仿真结果证明了该结构的功能是正确的。该器件的最大上升时间为2ps，对比度约为8.08 dB，结构面积约为2790µm2。

Designing ultra-fast all-optical full-subtractor using the photonic crystal structure

In this paper, a photonic crystal-based structure for an all-optical full-subtractor has been proposed. The structure includes six nonlinear resonant rings to transmit the incoming optical waves toward the output ports. Using the different radii for nonlinear rods made the possibility of the dropping operation for different amounts of optical intensities. The nonlinear rods are made of a doped-glass with an optical Kerr coefficient of 10–15 m2/W. To calculate the components of the optical waves throughout the structure, the finite-difference time-domain method has been used. The simulation results prove the correct functionality of the proposed structure. Besides, the maximum rise time of the device is equal to 2 ps. The contrast ratio and the area of the structure are around 8.08 dB and 2790 µm2, respectively.
