Abstract
We propose to research and develop a new type of quantum dot (QD) mode-locked laser based on new active region and cavity designs. The cavity design will use a low loss QD/waveguide active region combined with index confinement through selective oxidation to enable cavity lengths greater than 1.5 cm that retain high optical extraction efficiency. The active region is designed with the goal of enabling mode locked operation at drive levels well above threshold to reach high peak powers. The mode locked QD laser will be designed for monolithic integration with a high gain optical amplifier using the same QD active material and waveguide to further increase the pulsed power from the laser. The key features of the new design are based on the potential to achieve very low internal loss in the QD active region, and its combination with low loss index confinement based on selective oxidation. Package development for low stress mounting and thermal management, along with device modeling, will be performed in the Phase I for device integration. The Phase I work will include laboratory demonstrations of high peak power mode locking at 1.3 m and QD active region development for extension to longer wavelengths.
