Paper Abstract

We demonstrate temperature-insensitive eye-opening under 10-Gb/s direct modulation of 1.3-μm p-doped quantum-dot lasers without current adjustments, which show 6.5-dB extinction ratio between 20 and 70°C. The active region consisting of ten quantum-dot layers with p-type doping enabled this highly temperature-stable dynamic performance, much superior to conventional 1.3-μm quantum-well lasers. This result opens a way to uncooled 1.3-μm quantum-dot lasers without current adjustments.
