一、工作原理磁光调制器由秘取代的铁石榴石簿膜所制成,该薄膜生长在非磁性透明基片上,铋的单轴各向异性场矢量取向垂直于薄膜的平面,而场矢量强度大于薄膜的磁饱和强度.该薄膜采用蚀刻的方法构成如图1扫描电子显微镜图象中所示的台面(晶体管).导线采用常规的半导体制造技术沉积在薄膜上面,构成改变每个台面或象素的磁场矢量方向所需的激励线路.为便于透射式或反射式使用,应使导线的几何形状最佳化.图2示出透射式阵列的一个例子,图中128×128象素 First, the working principle Magneto-optic modulator by secret substitution iron garnet film made of the film is grown on a non-magnetic transparent substrate, bismuth uniaxial anisotropic field vector perpendicular to the film plane, and the field vector The intensity is greater than the magnetic saturation of the film.The film is etched to form a mesa (transistor) as shown in the scanning electron microscope image of Figure 1. The wire is deposited on top of the film using conventional semiconductor fabrication techniques, The excitation lines required for the direction of the magnetic field of the pixel should be optimized for the transmissive or reflective use Figure 2 shows an example of a transmissive array in which 128 x 128 pixels
