Abstract
This dissertation presents a comprehensive study on the coupling of dibenzoterrylene (DBT) quantum emitters to both free space and integrated photonic structures, aiming to pave the way for advancements in quantum communication and computing technologies. By exploring the intricate interactions between light and matter at the quantum level, this work delves into the potential of organic molecules as reliable single-photon sources, a critical component for quantum information processing. Through detailed analysis and numerical simulations, the thesis elucidates the chemical and optical properties of DBT molecules embedded in anthracene crystals (DBT-Ac), highlighting their suitability for high- efficiency quantum emission. The research further investigates the application of direct laser writing (DLW) techniques to create photonic architectures tailored for enhancing the performance of quantum emitters. By leveraging two- photon absorption phenomena, the DLW method allows for the fabrication of structures with superior resolution, essential for minimizing losses and optimizing emitter-structure coupling. Theoretical and practical aspects of eigenmode simulations, full-wave frequency domain simulations, and radiation pattern analyses are meticulously examined to provide a foundational understanding of emitter behavior in various photonic environments. Significant findings from this thesis demonstrate the enhanced quantum emission efficiency and improved control over photon emission properties through optimized coupling to designed photonic structures. These advancements not only contribute to the theoretical understanding of quantum emitter-photonics coupling but also offer practical insights into fabricating next-generation quantum devices.
