Abstract

This paper examines the use of an FPGA to circumvent the redundancy that may occur in free-space optically interconnected systems. We believe this paper presents solutions to the mapping of emitters and detectors onto an optoelectronic interface in order to perform an efficient connection topology. We report a novel versatile arrangement of the input/output optical interface and a straightforward algorithm for the implementation of a completely connected topology. Both utilize the reconfigurable potential of the FPGA to ease the design constraints on the optical system.
