| The area of Microwave Photonics (MWP) is considered on one aspect as the manner of using optoelectronic devices and systems to manipulate microwave systems and on the other aspect as the study of optoelectronic devices and systems that generate and process signals in the range of microwave frequencies. Among several applications from this last aspect, this work considers a simple and easy configuration of Microwave photonic filters (MPFs) and Optoelectronic oscillators (OEOs). The MPFs are arrangements designed with the aim of carrying similar tasks to those of an electrical microwave filter within a radio frequency system, contributing supplementary advantages inherent to photonics such as low loss, high bandwidth, immunity to electromagnetic interference, reconfigurability, and tunability. Precisely, one of the goals of this thesis work is devoted to proposing alternatives of tunability for a particular bandpass MPF. In this way, the novelty of this work resides in the use and analysis of a Fabry-Perot filter to obtain in a dynamic way the tunability of microwave bandpass. Even more, another particular technique to achieve tunability is studied and implemented. In particular, a pair of Distributed Feedback (DFB) lasers, and a Semiconductor Optical Amplifier (SOA) are proposed for this goal. The OEOs are other photonic arrangements that allow the generation of highly pure microwave signals. For our case, a particular OEO is designed by adding an optoelectronic loop to the basic configuration of the MPF previously mentioned. Like an MPF, frequency tunability for the OEOs is a topic of much interest too. Thus, this thesis work comprises a study to obtain the tunability of an OEO. The tunability is achieved by modifying the intermodal separation (δλ) of the multimode source. The results from both proposal techniques are supported by a series of simulations, corroborated by values computed theoretically, and verified in an experimental way. The tunability of these MWP systems is successfully achieved. For the case of the OEO, this work presents for the first time, to our knowledge, a gradual tuning map demonstrating the system tunability. An analytical method to determine the phase noise (PN) is presented in order to evaluate the performance of the OEO. Compared to the theory, the obtained PN values show a good performance of our implemented OEO. | |
