Abstract :
We propose and experimentally demonstrate a scheme for the generation of wavelength-tunable pulses from two mutually injection seeded Fabry-Perot laser diodes. The wavelength tuning is achieved by electrical control of the delay time between two RF signals driving the lasers. A linear tuning characteristic is obtained at a constant operating frequency of 1 GHz. The output has a sidemode suppression of about 30 dB across a tuning range of 15 nm.
