High-speed InP-based quantum dot lasers with low temperature sensitivity

We report temperature insensitive high speed InAs/InP quantum dot lasers. At 14°C-60°C, the bandwidth is respectively 15–13GHz, at 8°C it is 8GHz. 25Gbit/s under constant drive parameters at 14–60°C and 32Gbit/s at 14°C were demonstrated.
