ALL-FIBER, VERSATILE FEMTOSECOND SOLITON SOURCE WITH BROAD WAVELENGTH AND REPETITION-RATE TUNING RANGES

摘要

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.
