    Abstract

    The photonic nanowire single-photon source design approach allows for efficient broadband coupling between a quantum dot and a 1D photonic environment. In this work, we introduce weak cavity effects to the design by implementing a distributed Bragg reflector in the inverted taper. This leads to broadband enhancement of the photon emission rate with a Purcellfactor of 6 over a full-width half-maximum range of 20 nm while maintaining a total outcoupling efficiency of 0.8 to a Gaussian profile.
