Mach–Zehnder electro-optic modulators chirping management in high speed data communication lightwave systems

Abstract This work demonstrates Mach–Zehnder electro-optic modulators chirping management in high speed data communication lightwave systems. The link with applied voltage on the modulators arms is clarified. We have analyzed the chirp in MZ lithium niobate modulators output. The resulted signal passed on the channel that consists of the loop control that we used not to lose too much power because we use an amplifier after a period of fiber reach cable. The resulted signal distance depends on the number of loops multiplied by the fiber reach cable. The next step is to receive the signal by photodetector pin with a responsivity of 1 A/W. The signal after that passed on low pass Gaussian filter with a cut of bandwidth of 0.75 × Bit rate.
