Paper Abstract

In this paper we implement and characterize a two-channel optical programmable beamformer. The system is designed to achieve four-bit resolution. The architecture of the programmable dispersion matrix is based on an array of four delay-lines each having two spliced fiber Bragg gratings. We have experimentally investigated the optical signal processing performance of the optical beamformer in receive and transmit modes. Beampatterns for RF range 40 - 200 MHz are presented along with the theoretical calculations. The main lobe of the beampattern is shown to be independent of frequency for several target positions thus demonstrating a “squint-free” characteristic of this optical processor.
