Abstract
We demonstrate a simple self-seeding scheme for generating dual-wavelength single mode picosecond pulses at a fixed repetition rate with a Fabry-Perot (F-P) laser diode. The F-P laser diode was self-seeded from two fiber gratings that acted as wavelength filters. About 2GHz dual-wavelength pulses with widths of about 45ps and 75ps were achieved when the lengths of external cavities corresponding to different wavelength were equal or different.
