我们在不使用任何电流调节的情况下，在10gb /s直接调制1.3 μ mp掺杂量子点激光器下演示了温度不敏感的睁眼。激光器在20°c和70°c之间的消光比为6.5 db。一个由十个量子点层组成的p型掺杂有源区域实现了这种高度温度稳定的动态性能，这远远优于传统的1.3 μ m量子阱激光器。这些结果使得不需要任何电流调整就可以使用非冷却的1.3 μ m量子点激光器成为可能。
We demonstrate temperature-insensitive eye-opening under 10-Gb/s direct modulation of 1.3-mum p-doped quantum-dot lasers without using any current adjustments. The lasers show a 6.5-dB extinction ratio between 20degreesC and 70degreesC. An active region consisting of ten quantum-dot layers with p-type doping enabled this highly temperature-stable dynamic performance, which was much superior to conventional 1.3-mum quantum-well lasers. These results make it possible to use uncooled 1.3-mum quantum-dot lasers without any current adjustments.
