Summary:Optical interconnections suitable for three-dimensional combining
of lens arrays are presented. A multistage interconnection network with
a self-routing function is described. The number of light paths this
network is estimated to be capable of handling roughly ten or more times
that of previously reported self-routing networks. Two separate lens
arrays were fabricated to construct an 8×8 network of this design.
The feasibility of the proposed interconnections was successfully
demonstrated
