Improvement of Input Power Dynamic Range and Extinction Ratio for Wavelength Converters Based on Cross-Gain Modulation

Impact of extinction ratio of single arm sin2 LiNbO3 Mach–Zehnder modulator on the performance of 10 and 20 Gb/s NRZ optical communication system

“…They showed that crosstalk (X talk) level is dependent on the pump power and the dispersion of the fibers. Joon-Hak et al [13] presented a technique for improving the input power dynamic range and extinction ratio of wavelength converters based on cross-gain modulation in a semiconductor optical amplifier.…”
