Abstract: Dual-wavelength optical picosecond pulses are generated simultaneously by using a multiple-optical-path self-seeding scheme. The external cavity of the Fabry–Perot (F–P) laser diode consists of three fiber Bragg gratings (FBGs) and a variable optical delay line. The wavelengths of the optical short pulses can be selected conveniently by adjusting the FBG and switched simply by adjusting the optical delay line. A side mode suppression ratio of better than 18 dB is achieved by using a 1:99 optical coupler to enhance the seeding power. The system is simple, easy to operate, and low cost.
