We demonstrate an all-optical reconfigurable logic gate based on dominant nonlinear polarization rotation accompanied with cross-gain modulation effect in a single semiconductor optical amplifier (SOA). Five logic functions, including NOT, OR, NOR, AND, and NAND, are realized using 10-Gb/s on-off keying signals with flexible wavelength tunability. The operation principle is explained in detail. By adjusting polarization controllers, multiple logic functions corresponding to different input polarization states are separately achieved using a single SOA with high flexibility.

Quantum walks, a counterpart of classical random walks, have many applications due to their neoteric features. Since they were first proposed, quantum walks have been explored in many fields theoretically and have also been demonstrated experimentally in
利用数值模拟方法,采用桶中功率为86.5%定义的环围功率束宽作为光束扩展的评价参数,研究了环状光束在大气湍流中沿斜程路径传输的光束扩展。研究结果表明,自由空间中遮拦比越大,远场光强旁瓣越明显。大气湍流造成光强旁瓣消失,且远场光强分布并不是高斯分布。光束扩展随着遮拦比和天顶角的增大而增大,大气湍流对光束扩展的影响也随天顶角的增大而增大。当遮拦比较大或较小时,湍流对光束扩展影响随遮拦比的增大而减小;当遮拦比中等大小时,湍流对光束扩展的影响几乎不随遮拦比而变化。与已有研究结果比较发现,按照桶中功率不同百分比定义
建立有效的观测模型去区分目标与背景是实现稳健跟踪的核心。提出了一种基于多特征观测的红外目标跟踪算法。灰度特征、局部标准差特征和梯度特征均以直方图的形式描述目标外观;目标观测模型的构建则根据环境自适应权衡了以上三个特征,相应的各特征权值的动态选择通过最大化目标与其他图像区域的差异完成。在粒子滤波框架下,实现目标运动状态的估计与多特征权值的选择。真实场景实验结果表明,该算法在目标外观高动态、背景强杂波
