Abstract
The high frequency properties of InAs/GaInAs quantum dot distributed feedback (DFB) lasers emitting at 1.3 μm have been examined. The lasers display a small static linewidth of 1.3 MHz and a chirp as low as 83 MHz/mA. More than 5 GHz small-signal modulation bandwidth was observed in the first devices indicating the potential for high-speed operation of quantum dot lasers
