Abstract
Light is diverted from one optical conductor to another optical conductor by a suitably oriented non-planar reflecting surface at the junction of the two optical conductors. The non-planar surface comprises facets arranged so that light incident on one facet from one optical conductor will be reflected at that facet onto an adjacent facet, and at the adjacent facet to the other optical conductor. The arrangement of facets is such that the Snell's Law condition for total internal reflection at each facet can be satisfied for a wider range of ray directions than is possible for a single planar reflecting surface. The arrangement is useful for optical backplanes now being proposed for use in computers and telecommunications equipment.
