Abstract

Boolean logic gates are essential components for optical computing and communication systems. However, most existing methods for realizing them require complex structures, high power consumption, or multiple devices. Here, we propose a simple and compact system that can realize five Boolean logic gates, including AND, NAND, OR, NOR, and NOT, by applying different polarization modes and tuning intensities to the input signals within a SOI resonator system, formed by two nested micro rings in a racetrack ring resonator (TNMIRTR). A formula was derived for the optical transfer function of the system using the delay-line-signal method and the logic gates were simulated using the variational finite-difference time domain (varFDTD) method. The proposed structure operates by combining amplitude and polarization-conversion. TNMIRTR gate has several advantages, such as its micro-scale size, low cost, and ability to realize multiple logic gates within a single layout.

在赛道环形谐振器中使用两个嵌套微镜的全光 AND、NAND、OR、NOR 和 NOT 逻辑门

布尔逻辑门是光计算和通信系统的重要组成部分。然而，现有的大多数实现方法都需要复杂的结构、高能耗或多个器件。在这里，我们提出了一种简单而紧凑的系统，通过在由赛道环形谐振器（TNMIRTR）中两个嵌套微环形成的 SOI 谐振器系统内对输入信号应用不同的偏振模式和调谐强度，可以实现五个布尔逻辑门，包括 AND、NAND、OR、NOR 和 NOT。利用延迟线信号法推导出了该系统的光传递函数公式，并利用可变有限差分时域（varFDTD）法对逻辑门进行了仿真。所提出的结构结合了振幅转换和偏振转换。TNMIRTR 逻辑门具有多种优势，如尺寸小、成本低，并能在单一布局内实现多个逻辑门。
