Abstract
A computer system that includes a plurality of processing elements for parallel computation utilizes a free-space optical network for communication between the processing elements. Such a network employs an optoelectronic switch that includes a binary H-type tree for routing signals to selected ones of an array of lasers. Hybrid repeaters are included in the optical paths to generate output optical beams colinear that are with incident input beams.
