title: Beam-array combination with planar integrated optics for three-dimensional multistage interconnection networks.
abstract: We propose a configuration of planar integrated optics for three-dimensional multistage interconnection networks. To show the feasibility of cascading operations in the planar integrated optics, we present experimental results on the beam combination of signal- and power-beam arrays at a node stage. The beam-combination efficiency measured in the experiment is ~42% of the theoretical limit.
