Stability and environmental control during operation is one of the necessary requirements desired for quantum-technological applications. The most promising way for such control of the surrounding is the direct integration of all required components on one chip. The most advanced and versatile platform for the implementation of highly complex and scalable photonic logic is the silicon platform. In this work, we utilize and optimize designs of photonic cavities in order to obtain high coupling efficiencies of quantum emitters to silicon waveguides. We will discuss how quantum emitter positioning will modify the light-matter interaction and how we can achieve best performance. Furthermore, radiation diagrams of TE and TM modes for the guided modes and free space modes are investigated in order to reduce radiative losses and maximize the coupling to the waveguides.
