We demonstrate the reduction of phase noise 10 dB below the thermomechanical noise limit of individual oscillators in arrays up to seven synchronized self-sustaining optomechanical oscillators.
We demonstrate optomechanically induced amplification of carbon nanotube (CNT) mechanical modes using optical microcavities. We also show direct imaging of the spatial profile of CNT mechanical modes using optical readout.
We design and fabricate a 2 × 2 optomechanical oscillator array. We show the onset of synchronized mechanical oscillations when the array is excited by a single continuous wave laser.
We show that two independent mechanical oscillators, placed ∼3.2km apart, and separated in frequency by ∼80kHz, can be locked in a master-slave configuration, using light. This scheme can be generalised for an arbitrary network configuration.
We couple a single suspended carbon nanotube to the near field of a free standing optical microdisk. The strong interaction between the nanotube and the microcavity produces an ultrahigh photocurrent response as large as 0.35mA/W.
We theoretically and experimentally demonstrate that the support loss of double-disk optomechanical resonators can be minimized using destructive elastic wave interference. We show 100MHz Si3N4 resonators with mechanical quality factor of 104 at room temperature.
