Abstract

This work presents a theoretical study of harmonic generation of microwave signals after detection of a modulated optical carrier in cascaded two electro-optic modulators. Dispersion is one of the major limiting factors for microwave generation in microwave photonics. In this paper, we analyze influence of chromatic dispersion, dispersion slope, dispersion curvature on microwave generation using two cascaded MZMs and it has been found that output intensity of photodetector reduces when dispersion term up to fifth order are added. We have used the two cascaded Mach-Zehnder Modulators for our proposed model and tried to show the dispersion effect with the help of modulation depth factor of MZM, which have been not discussed earlier.

Keywords

Abstract

In this work, we tried to analyze the crosstalk in optical amplifiers. For mathematical analysis, we have considered the Gain (G) for different amplifiers as 35 dB, 18 dB and 26 dB, respectively.

Keywords

Bit Error Rate, Crosstalk, Optical Amplifiers, Power Penalty.
