Optical logic gates are key elements in all-optical circuits and computing. However, the footprints of current optical logic gates are still on micrometer scale. There remains challenging for further miniaturization of the logic gates to nanometer scale. In this paper, a simple scheme for realizing ultra-compact universal linear-optical logic gates is proposed. All common logic gates (AND, OR, NOT, NAND, NOR, XOR, and XNOR) encoded via binary phase shift keying are achieved by using single rectangle plasmonic slot nanoantenna with a footprint of 200 nm by 50 nm, which considerably shrinks the dimensions of the device.

基于单矩形等离子缝隙纳米天线的超紧凑型通用线性光学逻辑门

光学逻辑门是全光学电路和计算中的关键元素。但是,当前的光学逻辑门的占位面积仍为微米级。进一步将逻辑门小型化至纳米级仍然具有挑战性。提出了一种实现超紧凑通用线性光学逻辑门的简单方案。通过使用相移键控编码的所有常见逻辑门(AND,OR,NOT,NAND,NOR,XOR和XNOR),都是通过使用占位面积为200 nm x 50 nm的单矩形等离子缝隙纳米天线来实现的,这大大缩小了尺寸设备的
