In this paper, a 3-bit optical beamforming architecture based in 2/spl times/2 optical switches and dispersive media is proposed and demonstrated. The performance of this photonic beamformer is experimentally demonstrated at 42.7 GHz in both transmission and reception modes. The progress achieved for realizing these architectures with integrated optics is(More)
We present two concepts dedicated to the optical summation of RF signals for radar applications. The first technique relies on a photodiode simultaneously illuminated on its top and back sides. We experimentally demonstrate the summation of two signals covering the whole 25-GHz photodiode bandwidth with amplitude and phase errors below plusmn1dB and(More)
In this paper, several optical beamforming architectures are proposed and experimentally demonstrated. The progress achieved for realizing these architectures with integrated optics is also reported. Due to its advanced features (fast-switching, huge bandwidth, immunity to EMI) the proposed photonic integrated beamforming architectures are a very promising(More)
