Broadband Adaptive Feedforward Photonic Linearization for High Dynamic Range Signal Remoting

We present a novel architecture for an adaptive broadband high dynamic range photonic transceiver suitable for RF signal remoting in airborne platforms. The transceiver incorporates feedforward (FF) linearization to correct the electrical-to-optical (E/O) conversion nonlinearity as well as optimized control loops that enable the system performance to be maintained during changing operating conditions. We have verified the technical feasibility of the broadband adaptive linearized analog photonic circuit through theoretical and experimental investigations. The operation of the broadband linearized photonic transceiver in a traffic-carrying mixed data wavelength division multiplexed fiber network has also been demonstrated.
