A simple all-optical pulse generation technique based on gain-induced four-wave mixing in a semiconductor optical amplifier is introduced. The introduced concept is theoretically investigated and experimentally demonstrated. For a concept demonstration, 10 GHz and 42.5 GHz pulse trains are generated. A 20 nm central wavelength tunability is achieved.
