When tuned on resonance, two strongly coupled modes exhibit an avoided crossing with a splitting exceeding the linewidth of the two modes. The underlying coupling mechanisms can be manifold, and include dielectrically induced coupling, or coupling mediated by strain in a joint substrate or clamping point. We are striving to control the coupling strength both within a single and between neighboring resonators, with the goal to realize nanomechanical resonator networks.
