提出一种利用相位连续可调诱导产生的双艾里光束形成方形光瓶的方法。该方法首先利用二值化后的相位调制出双艾里光束, 为了能够实现光瓶能量分布, 一个可调控的线性因子被引入到相位调制函数中形成新改进的相位, 该相位能够灵活地调节光瓶的大小。数值模拟结果表明高斯光束通过该改进相位调制, 能够形成光瓶能量分布的光束。该方形光瓶光束可应用于光镊、原子捕获与操纵。

Abstract

We theoretically investigate the generation of square optical bottles, which are generated by a pair of symmetric Airy beams induced by a binary phase pattern. A regulable linear factor is introduced into the phase function to modulate flexibly the size of resulting optical bottle. Numerical simulations are performed and results show that a Gaussian beam can be shaped into a square optical bottle by a tunable binary cubic phase pattern. The linear factor can vary the size of zero or low intensity region of optical bottle. It is believed that the intriguing characteristic of square optical bottle can be applied in many applications such as optical tweezers, atom trapping and manipulating.
