光互连全交叉网络在巨型计算机和光子交换网络系统等领域具有十分重要的潜在应用。本文在自行设计研制成功棱镜光栅和65×65大列阵Dammann光栅的基础上，运用自由空间光学互连技术实现了64×64全交叉网络的互连函数。采用互连矩阵对输出图样进行了计算，结果与实验吻合。

Optical interconnection networks have important potential applications in the fields of super-computers and photonic switching network systems etc. Based on the prism gratings and the 65 ×65-array Dammann grating designed and fabricated by us, we implemented the 64 ×64 crossover interconnection functions by using free-space optical interconnection technology. Calculations about output patterns of crossover interconnection functions have been made, which are agreement with our experimental results.
