Abstract

In this paper, we propose and demonstrate a high linear analogue photonic link based on a Dual-drive Dual-parallel Mach-Zehnder Modulator (D-DPMZM) with Balanced Photo-Detector (BPD). Third order Intermodulation Distortion (IMD3) and Second-Order Distortions (SOD) products have been eliminated by controlling the phase of input RF signal and driving voltage of D-DPMZM. The proposed configuration of microwave photonic link is symmetrically single-sideband modulation in two D-DPMZM. For the proposed configuration and the purity of the system, mathematical modeling and simulations have been developed and tested by introducing additional RF signals. In addition, in the proposed configuration, a high linear down-converted signal is transmitted by changing only the operating modulator biasing point, from quadrature to maximum. The elimination of IMD3 and SOD products has been achieved simultaneously with suppressed higher order harmonic in this system. To the best of our knowledge, this is the first reported work in literature where IMD3, SOHs and second order distortion produces have been completely eliminated.
