ABSTRACT
The authors generate and compress short pulses via the ground and excited state transitions from a passively mode-locked grating coupled quantum dot two-section diode laser at a repetition rate of 2.7 GHz. The selection and isolation of either the ground state or excited state transition were performed by an angle tuning of the grating. The externally compressed pulse widths are 970 fs from the ground state and 1.2 ps from the excited state transition. The sign of the chirp is up chirped for both state transitions.
