A novel 2N beams heterodyne optical beamforming architecture based on N/spl times/N optical Butler matrices

Abstract

A novel beamforming architecture based on optical Butler matrices is proposed and experimentally evaluated. The optical Butler matrix operating principle and the effects of fabrication inaccuracies on the beamformer radiation pattern are presented. The proposed architecture offers simultaneous multibeam generation capability. 40 GHz RF phase measurements… (More)
