1.3 µm regrown quantum-dot distributed feedback lasers on (001) Si: a pathway to scale towards 1 Tbit/s

Regrown quantum-dot distributed feedback lasers on (001) Si demonstrated a SMSR of 50 dBm, a threshold current density of 440 A/cm², a CW operation temperature of 70°C, and a path towards high-volume, low-cost transceivers.
