Abstract: We report subpicosecond pulse generation at 22 GHz from a two-section passively mode-locked laser at 1.55$\mu{\rm m}$, 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${\sim}{\rm 280}~{\rm fs}$(1 Hz–100 MHz).
