Abstract

A novel scheme for generating multiwavelength short pulses in a self-seeded Fabry-Perot laser diode with a fiber external cavity using fiber Bragg gratings (FBG's) was demonstrated. In this scheme the external cavity length for all wavelengths selected by the gratings is intrinsically identical and the FBG's can be cascaded into the external cavity. Simultaneous generation of 1-GHz dual-wavelength short pulses with a wavelength separation of 1.6 or 18 nm was demonstrated. A sidemode suppression ratio (SMSR) better than 30 or 25 dB was achieved at both wavelengths in the former and latter cases respectively. Three-wavelength 1-GHz ps pulses with a SMSR better than 25 dB at all three wavelengths were also successfully generated.
