We report on hybrid integrated distributed feedback (DFB) lasers based on silicon
nitride waveguide stacks containing a layer of embedded colloidal quantum dots. The DFB laser
shows a low optical pumping threshold of 188 kW/cm2 and operates in a single mode regime. Our
results show the potential of colloidal QDs to hybridize silicon nitride photonic circuits and open
the way to novel functionalities on said platform.
