Abstract :
Summary form only given. High-repetition-rate, short-duration soliton trains in optical fibers have attracted considerable attention due to their potential application to telecommunications. Adiabatic Raman compression is a powerful technique for generating such trains and has been applied to the output of electro-absorption modulators (EAMs) and gain-switched diode lasers. We employed adiabatic Raman compression to obtain an 800-fs soliton train from a 20-GHz Mach Zehnder amplitude modulator generated sinusoidal pulse train that was wavelength-tunable over 20-nm around 1550 nm. 440-fs durations were obtained outside of the adiabatic regime.
