Abstract
In this paper, we present a mode-locked laser photonic integrated chip developed within a multi-project wafer run at an InP-based generic foundry. The 1.66-mm-long Fabry-Perot cavity is formed with two on-chip multimode interence reflectors in which four gain sections and three saturable absorbers equally divide the cavity in four. The fourth harmonic colliding pulse configuration supports pulse train generation of 100 GHz, corresponding to 0.8-nm mode spacing. Autocorrelation traces exhibit the ultrafast pulse widths as short as 0.5 ps. Terahertz dual-mode spectra are presented as well.
