| Resumo: | The field of cavity optomechanics has experimented an increase in interest due to its wide range of applications, from sensing to secure data communications. In this work, we review the main theoretical topics needed to comprehend optomechanical phenomena taking place in a silicon optomechanical cavity with the goal to synchronize two oscillating cavities. Synchronization of optomechanical (OM) cavities is a very new field of study where not many works have been published to date. With the aim of achieving synchronization of two OM cavities we first characterize their behavior in response to laser light in the near-infrared region of the spectrum where the cavities have been engineered to display both photonic and phononic band gaps. Once the optomechanical interaction has been characterized for each cavity, both cavities are brought to the conditions where synchronization is possible. In this report, synchronization cannot be fully confirmed although there is good evidence for it. |
