Abstract: | We show how to optimize design parameters for different electro-optical modulators where the effective refractive index plays an essential role in the evaluation of the bandwidth structure. We investigate the effect of operating parameters on the switching, modulating voltage, device performance index, and optical bandwidth for different material-based electro-optical modulators and evaluate the transmission bit rate using nonreturn-to-zero (NRZ) coding transmission technique. As well as lithium niobate (LiNbO3), gallium arsenide (GaAs), and polymethylmethacrylate (PMMA), polymer EOMs have been developed for extensive use in high-speed- and high-transmission-performance optical-fibertransmission systems. This is because they offer the advantages of modulation exceeding multi-Gbit/s combined with a low driving voltage. |
