Abstract

The field of integrated silicon photonics has been developing rapidly in the last years, leveraged by its capable of providing solutions to numerous current technological demands. In this area, microcavity-based photonic devices, like rings and disks, predominate and they are promises to contribute to the solutions that have been developed. Therefore, promoting the knowledge about the behavior of these devices and the physical phenomena involved in its operation is fundamental to generate new technological applications for the photonics. In this way, this project presents a proposal of detailed study about waveguides and integrated microcavities, which are capable of being coupled to create the so-called photonic molecules (PMs). These PMs allow the observation of relevant phenomenon, like "Dark States" and "Quasi-Dark States", that can generate new applications. One of the main objectives of this proposal is to investigate two important issues related to these phenomena: The influence of the coupling position between the microcavities in the transmission spectrum of the PMs and in the generation of the "Dark States" and "Quasi-Dark States". The answer to these questions can allow an important scientific advance for the photonics, since the phenomena explored here have potential to bring technological innovations.
