| Abstract: | This paper has presented the transmission performance evaluation of different electro‐optic modulators (EOM) for ultra high switching speed operations and applications. As well as the optimization design parameters for different EOMs have been investigated, where the effective refractive index plays an essential role in the evaluation of the bandwidth structure. The effects of the operating parameters on the switching, modulating voltage, device performance index, and optical bandwidth are also investigated for different material‐based EOMs, where the transmission bit rate is evaluated by using non‐return‐to‐zero coding transmission technique. As well as lithium niobate, gallium arsenide, and poly methyl metha acrylate polymer EOMs have been developed for extensive use in high speed and high transmission performance optical fiber transmission systems.
