2 December 1992 Integrated optical coherent architecture for beam forming in phased-array active antennas
Author Affiliations +
A new architecture is proposed for the optical beam forming in Phased Array Active Antennas (PAAA) in which the integrated optical technologies allow to realize a simple and effective coherent optical processor. The system proposed here combines the advantages of the microoptics systems (all optical processing) with the ruggedness and small size of the integrated optical circuits. These results are obtained by the use of optical multifunctional circuits integrated on LiNbO3 performing all the necessary processing. The resulting network consists of a single integrated optical chip for each antenna row and the optical fibers for the distribution of the signals (frequency, phase) to the active radiating elements. The system architecture will be discussed and technological results in the fabrication of the integrated optical circuit will be presented.
