Paper Abstract

A simple mutual pulse injection-seeding scheme is developed to produce tunable single wavelength and dual-wavelength optical short pulses by using two Fabry-Perot laser diodes. The operating wavelength of the optical pulses is flexibly selected by adjusting a tunable filter or cascaded fiber Bragg gratings, and the pulse intensity is enhanced by using an erbium-doped fiber amplifier. The sidemode suppression ratio achieved by the system for single wavelength operation is larger than 26 dB over the wavelength region of 25 nm and higher than 31 dB within 18 nm wavelength range. In the dual-wavelength case, the sidemode suppression ratio achieved is better than 25 dB over the wavelength-tuning range of 12.1 nm. The system is robust, flexible and convenient for wavelength tuning.
