Abstract (in Japanese) (See Japanese page) 
(in English) We have demonstrated ultrafast optical pulse generation using a Mach-Zehnder-modulator-based flat comb generator (MZ-FCG) and an adiabatic soliton compression technique. Our pulse generation technique is very simple configuration and has tunability in the repetition rate and the pulsewidth. The MZ-FCG was driven by two radio-frequency sinusoidal signals. Continuous wave lights led to the MZ-OFG were converted to ultraflat comb signals. The comb signals were formed into picosecond pulse trains by compensating the frequency chirp, and the picosecond pulses were compressed into femtosecond pulses by a dispersion flattened-dispersion decreasing fiber. Pulse trains with 200fs-width and repetition rate of 5-17GHz were successfully generated.
