High Power, Optical Feedback- Tolerant 1310 nm Quantum Dot DFB Lasers

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 operatio...

Summary: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.
