摘要

We have developed 1310 nm high power quantum dot distributed feedback lasers. Optical output power of >40 m W at $85^{\circ}\mathrm{C}$ was achieved with sidemode suppression ratio of >50 dB. Stable relative intensity noise against external optical feedback was observed under high power operation.
