We demonstrate an all‐fiber, widely wavelength, and repetition‐rate tunable soliton source using soliton self‐frequency shift (SSFS) in a single‐mode fiber. A 2‐ps actively mode‐locked fiber laser at 1550 nm incorporating a Mach–Zehnder modulator is used as a repetition‐tunable input source. The SSFS process results in a compressed, wavelength‐tunable femtosecond pulse. Versatility of the source is demonstrated through tuning of soliton wavelength from 1560 to 1700 nm, as well as arbitrary pulse sequence generation. © 2014 Wiley Periodicals, Inc.
