An optical multimode fiber (MMF) is capable of delivering structured light modes or complex images with high flexibility. Here, we present a holographic approach to enable the MMF as a 3D holographic projector with the capability of complete polarization control. By harnessing the strong coupling of the spatial and polarization degrees of freedom of light propagating through MMFs, our approach realizes active control of the output intensity and polarization in 3D space by shaping only the wavefront of the incident light. In this manner, we demonstrate MMF-based holographic projection of vectorial images on multiple planes via a phase-only hologram. Particularly, dynamic projection of polarization-multiplexed grayscale images is presented with an averaged Pearson correlation coefficient of up to 0.91. Our work is expected to benefit fiber-based holographic displays, data transmission, optical imaging, and manipulation.

使用多模光纤进行矢量图像的动态 3D 全息投影


光纤多模光纤 (MMF) 能够以高度灵活性提供结构光模式或复杂图像。在这里，我们提出了一种全息方法，使 MMF 成为具有完全偏振控制能力的 3D 全息投影仪。通过利用MMF传播的光的空间自由度和偏振自由度的强耦合，我们的方法通过仅塑造入射光的波前来实现3D空间中输出强度和偏振的主动控制。通过这种方式，我们通过纯相位全息图演示了基于 MMF 的矢量图像全息投影在多个平面上。特别是，偏振复用灰度图像的动态投影的平均皮尔逊相关系数高达 0.91。我们的工作预计将有利于基于光纤的全息显示、数据传输、光学成像和操纵。
