摘要： A system and method are provided which includes ring resonator structures coupled together with beam structure(s). The ring resonators are configured to operate in the contour or breathe mode. The center of the coupling beam structure is used as a nodal anchor point for anchoring the ring resonators and the beam structures, and also provides a reflecting interface. In an embodiment, the coupling beam structure includes two quarter-wavelength matched beams and an anchor located at a nodal point for coupling the two quarter-wavelength matched beams and ring resonator structures. The symmetric ring design also provides a differential drive and sense configuration while balancing the driving forces about the anchor located at the center of the beam structure. The system exhibits low energy losses while providing large sensing signals and a high quality factor (Q) of about 186,000 at a resonant frequency of about twenty-nine (29) MHz.
