Abstract
Butt-joint integrated-extended cavity InAs/InP (100) quantum dot (QD) Fabry-Pérot laser devices emitting around 1.55 μn are demonstrated. Continuous wave lasing at room temperature is realized with devices of different lengths. The threshold currents, transparency current density, and external differential quantum efficiency are all comparable to those of all-active QD lasers. The Butt-joint reflectivity for straight waveguides is below - 40 dB. Light versus current curves and lasing spectra reveal that for low current, lasing starts on the QD ground state transition, while excited state lasing sets in with increasing current.
