摘　　要：采用光学全息的方法制备互连元件 (布喇格衍射型体积相位光栅 )。当光束垂直入射该光栅时 ,只有 0级透射光和 + 1级衍射光 ,可以较容易地得到直连、交叉光束 ,实现 2 *free space optical networks is well displayed by the way of holography with Bragg grating,which features high diffractive efficiency of 95% at most.0 level diffractive light is used as the straight line and 1 level as cross line.The experiments show that the cross network is well implemented.
