摘要：

A simple and robust system is presented to generate wavelength-tunable optical short pulses by use of two gain-switched Fabry-Perot laser diodes in a mutual pulse injection-seeding scheme. The operating wavelength of the optical pulses is flexibly selected by adjustment of a tunable filter, and its intensity is enhanced with an erbium-doped fiber amplifier. The side-mode suppression ratio achieved by the system is larger than 26 dB over a wavelength region of 25 nm and higher than 31 dB within an 18-nm wavelength. (C) 2003 Optical Society of America.
