Abstract

We describe and demonstrate a scheme to implement arbitrary space-variant optical interconnections with equal path lengths in free-space, using a layered structure for a low gate count and high throughput. We discuss extending the technique to reduce the number of layers by performing small group interconnections on laterally separable locations.
