Heterogeneously integrated III–V on silicon distributed feedback lasers at 1310 nm

We report performances of III–V/Si distributed feedback lasers at 1310 nm. Continuous wave regime is achieved up to 55°C, with room-temperature threshold of 35 mA, while mode-hope-free operation with side-mode suppression ratio above 55 dB is measured. The −3dB bandwidth is 6.7 GHz.
