Paper Abstract

The chirp and optical extinction ratio of multiple quantum well Mach-Zehnder modulators and electroabsorption modulators depend on the device design and the modulating voltage waveform. For transmission over non-dispersion shifted fiber, 10 Gb/s system performance is reviewed by considering joint optimization of the bias and modulation voltages. The implications of modulator design are examined taking into consideration group velocity dispersion and self-phase modulation arising from the Kerr nonlinearity. The results demonstrate that optimization of the bias and modulation voltages is effective for increasing the transmission distance, reducing the variation in performance obtained when Mach-Zehnder modulators of different designs are operated with maximum optical extinction ratio, and reducing the variation in performance obtained with different transmitted powers when electroabsorption modulators are operated with maximum optical extinction ratio.
