Abstract
This paper investigates the effect of crosstalk in optical cross-connect (OXC) utilizing MZI (Mach–Zehnder Interferometer). It is observed that (Voltage Optical Attenuator)–MZI has low cross-channel interference and the proposed structure reaches its efficient behavior, showing an error rate of ~ 10−18, a quality factor of 22.082, crosstalk of − 25.59523 dB, and switching time of 0.528 ns. The crosstalk for MZI–OXC varies between − 27.02 and − 18.27 dB for 400 GHz, and − 26 to − 17.74 dB for 200 GHz channel separation, respectively. The performance is compared with Fiber Bragg Grating and semiconductor optical amplifier-based configurations. The effect of crosstalk utilizing Gaussian and Butterworth filters is also illustrated.
