摘要：
In this Letter, we report observations for the optomechanical oscillator (OMO) synchronization in an air-slot photonic crystal (PhC) cavity driven by a single laser source. Two very-close mechanical modes are found in the air-slot PhC OMO cavity and can be locked to each other at drive powers above the threshold with different detunings. The improvement in phase noise (-70 dBc/Hz at 10 kHz offset) for the synchronized OMO is reported as well. The stable frequency tones obtained open a path toward reconfigurable synchronized oscillator networks. Published by AIP Publishing.
