Abstract

We propose a new type of magneto-optical (MO) Spatial Light-Modulation device, driven by spin-polarized current flow, i.e. Spin Transfer Switching (STS-SLM). Its basic operation and characteristics were experimentally confirmed. The proposed SLM device has a spatial resolution as small as several hundred nanometers, and an ultra-high drive speed of several tens of nanoseconds, and its basic operation is possible without active devices. Unlike, existing SLM devices, this device meets both the size and speed requirements of SLMs for use in displaying holographic three-dimensional (3D) moving pictures. To improve SLM device light modulation functionality, we carried out studies on magnetic films with perpendicular magnetic anisotropy to obtain large MO signals, which enabled us to perform improved light modulation performance. In addition, we obtained an MO signal that was thirty times larger than that possible with in-plane anisotropy. We conclude that this type of MO-SLM device is appropriate for displaying future super-high definition, holographic 3-dimensional moving images.

一种自旋极化电子驱动的超高清空间光调制装置

我们提出了一种新型的磁光空间光调制器件，由自旋极化电流驱动，即自旋转移开关(STS-SLM)。实验证实了它的基本工作原理和特点。该SLM器件的空间分辨率小至几百纳米，驱动速度高达几十纳秒，无需有源器件即可实现基本操作。与现有的SLM设备不同，该设备满足用于显示全息三维(3D)运动图像的SLM的尺寸和速度要求。为了提高SLM器件的光调制功能，我们对具有垂直磁各向异性的磁薄膜进行了研究，以获得大的MO信号，这使我们能够实现改进的光调制性能。此外，我们获得的MO信号比平面内各向异性的信号大30倍。我们得出结论，这种类型的MO-SLM器件适合显示未来的超高清全息三维运动图像。
