Abstract

Planar-integration of free-space interconnection systems has been proposed in order to reduce alignment problems and to provide smaller, robust and monolithic component [1-5]. This approach allows compact, non-blocking and bi-directionnal optical connection. They can be divided into passive and active components. Passive links are static and cannot be modified, they just offer a path for light between two processors. On the other hand, active interconnection are dynamic and can be reconfigured by controlling switching elements.
