Beam-array combination with planar integrated optics for three-dimensional multistage interconnection networks

摘要

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 similar to 42% of the theoretical limit. (C) 1997 Optical Society of America.
