摘要

A simple self-seeding scheme is developed to generate tunable dual-wavelength optical short pulses in a flexible manner and with an increased wavelength-tuning range. The wavelength selection and tuning are achieved by simultaneous use of a fiber Bragg grating and a tunable optical filter. The side-mode suppression ratio of the output pulses is better than 30 dB over a wavelength-tuning range of 33.8 nm. The system is compact and convenient for dual-wavelength tuning.
