Abstract
We propose and experimentally demonstrate a two-dimensional optical architecture, based on polarization switching by N spatial light modulators of p x p pixels, which provides 2 exp N-1 time delays values and an analog control of the 0- to 2-pi phase for each of the p x p microwave signals actuating an active antenna. These signals originate from the coherent detection of a dual frequency laser beam obtained with an acoustooptic frequency shifter. Experimental results obtained at a microwave frequency of 1.8 GHz are presented.
