Optoelectronic devices attracted considerable attention in many branches of science and technology, which can be attributed to their unique properties. Many of them use optical cavities which parameters can be adopted to specific requirements. This thesis investigates the introduction of diamond structures (nitrogen-doped diamond film, boron-doped diamond film, undoped diamond sheet) to optical cavities to tune their finesse coefficient. Moreover, their application enabled development of a system for optical monitoring of electrochemical reactions. A detailed review of the state-of-the-art presents techniques of cavities tuning in optoelectronic devices, diamond applications in optoelectronics and current solutions combining optical and electrochemical measurement techniques in one system is presented. The work includes mathematical investigation, description of the construction of cavities and measurement setup, as well as results of experimental measurements. Applications of optical cavities tuned by the use of diamond structures are presented on the example of fiber-optic sensors: for measurements of distance and liquids refractive index, and for construction of a hybrid optoelectrochemical system.
