We report subpicosecond pulse generation at 22 GHz from a two-section passively mode-locked laser at 1.55 µm, using a novel AlGaInAs quantum-well wafer. By carefully designing the metal pad and the isolation layer, we are able to hybridly mode-lock the laser by modulating the saturable absorber at the fundamental repetition rate and thus achieve a low timing jitter of ∼280 fs (1 Hz-100 MHz).
