Two gain-switched Fabry–Pérot laser diodes have been used in a self-seeding scheme for widely tunable dual-wavelength optical short pulse generation. The wavelengths and their spacing can be tuned in a flexible manner by adjustment of the wavelength-selective elements that consist of a fiber Bragg grating and a tunable optical filter. The side-mode suppression ratio of the output pulses achieved is better than 26 dB over a wavelength-tuning area of approximately 30 nm.
