“…[5] to [6] required highly calibrated coherent detector, which can increase instability of the used system. In [7] Various methods have been demonstrated to verify the suppression of IMD3 spurious components & to get the analytical investigation about the enhancement of SFDR [9][10][11][12][13][14][15][16][17][18]. MZM is the commonly used modulator in the RoF link and its inherent nature to exploiting the non-linear behaviour, but we are using this one due to its high stability and spectral purity.…”

This paper demonstrates the analytical approach of Linearized Radio over Fiber (RoF) link based on Dual-Drive Dual Parallel Mach Zehnder Modulator (DD-DPMZM) by properly adjusting the phase shifters and biasing of the Mach Zehnder Modulator (MZM). Two input RF tones at 7 and 8 GHz applied in the used RoF link. The proposed RoF link consists of Mach Zehnder Modulator (MZM), Parallel combination of Mach Zehnder Modulators, optical ber and photodetector (PD). Third Order Intermodulation Distortions (IMD3) factor act as a major issue, which is responsible as performance degradation factor. Major sources of IMD3 spurious components have been investigated and suppressed in theoretical analysis before photodetection. The proposed method is designed with the help of OptSim simulation software, to con rm and validate the analytical analysis and simulation results. Analytical analysis & simulation results show that, 40 dB suppression found in IMD3 spurious components, and 30 dB Hz 2/3 enhancement found in Spurious Free Dynamic Range (SFDR), for the proposed linearized RoF link as compared to conventional MZM RoF link.

filter could be achieved. Besides, we have also theoretically analyzed and experimentally investigated the evolution of interferometric spectral fringe visibility under different applied RF signal voltages, and the critical voltage of about 9 V has been found to acquire the maximum interferometric fringe visibility. Our proposed bandpass filtering scheme has several distinguished features such as fiber-compatibility, interferometric type spectral shape, spectral reconfigurability, and excellent spectral tunability, which could find promising applications in future optical communication systems.
