| Sumario: | The coupling between optical and mechanical waves within optical resonators has become a growing study field in the last years due to its scientific and technological importance. Optomechanical crystals (OMCs) are a means not only to achieve this interaction but to create coherent phonon sources required in many applications. This work aims for the synchronization of two OMCs acting as OM oscillators using light as the main coupling mechanism. A characterization of their experimental properties and dynamics is presented, as well as the mechanism to achieve frequency locking when they are brought to the ”phonon lasing” regime. Although synchronization is confirmed in the frequency domain, an improved set of OMC samples is needed to obtain a more efficient process. |
