Near-unity Efficiency in Ridge Waveguide-based On-chip Single-photon Sources

In this paper, a design for pursuing a near-unity coupling efficiency in quantum dot cavity ridge waveguide single-photon sources is presented. Simulations are performed to achieve constructive interference and low scattering losses within the cavity and to overcome the issue of the mode mismatch of the cavity and the Bloch mode in the nanobeam.
