N2 - Oscillators are systems that produce stable periodic signals without external frequency reference. A typical oscillator consists of a resonator that determines the output frequency, and an external sustaining feedback scheme to replenish the energy loss due to the dissipation from the resonator. Here we demonstrate that, by driving the constituent resonator to the internal resonance (IR) condition, where two different vibrational modes of the same resonator are coupled commensurately, there is efficient coherent energy exchange between the two modes. This strong coupling allows the observed mode to draw stored energy from the coupled mode, hence maintaining both its oscillation amplitude and frequency without an external power supply.
