光学涡旋由于其模式正交性而提供高维编码，因此受到了广泛的关注。本文演示了二维异或（XOR）逻辑运算使用的光束携带的光学涡旋阵列。它是用液晶空间光调制器实现的，以创建光涡旋的正交态作为输入参数。这种光学实现异或运算的方法可以为高维数据处理、密码学和计算带来新的可能性。本文还展示了XOR操作的光学涡旋阵列，使加密的二进制图像。
Optical vortices have gained considerable attention as they offer high-dimensional encoding owing to their mode orthogonality. This paper demonstrates two-dimensional exclusive-OR (XOR) logic operation using a light beam carrying an array of optical vortices. It has been implemented with a liquid crystal spatial light modulator to create orthogonal states of optical vortices as input arguments. The proposed approach to optically implement XOR operation can bring new possibilities for high-dimensional data processing, cryptography, and computing. The paper also shows XOR-operated optical vortex array enabled encryption of a binary image.
