Abstract
The temperature dependence of the dynamic performance of p-doped InAs/GaAs quantum-dot distributed feedback (DFB) lasers emitting at 1.3 μm is investigated. A maximum relaxation frequency of ~7 GHz is demonstrated for a constant bias current over the whole 25°C-85°C temperature range. The Henry factor is temperature independent and remains constant at ~2.5. The effect of external optical feedback is assessed on the same device in a 10-Gb/s transmission over 20 km.
