Abstract
The coupling between single photon emitters and integrated photonic circuits is an emerging topic relevant for quantum information science and other nanophotonic applications. We investigate the coupling between a hybrid system of colloidal quantum dots and propagating modes of a silicon nitride waveguide system. We furthermore explore the local density of optical states of the system by using a scanning probe technique and find that the quantum dots couple significantly to the photonic circuit. Our results indicate that a scalable slot-waveguide might serve as a promising platform in future developments of integrated quantum circuitry.

In this article we explore an approach to emitterwaveguide interaction based on the coupling of colloidal quantum dots to modes supported by two closely spaced Silicon Nitride (SiN) waveguides
Since the density of emitters along the waveguide was large, we could not conclude from the acquired measurements whether a change in lifetime is due to coupling to the propagating modes or due to the high density of colloidal quantum dots [21,22,23]
