We have demonstrated WSi-based superconducting nanowire single-photon detectors coupled to SiNx waveguides with integrated ring resonators. This photonics platform enables the implementation of robust and efficient photon-counting detectors with fine spectral resolution near 1550 nm.
We demonstrate an optomechanical accelerometer using a v-groove fiber coupled photonic-crystal nanocavity integrated with a high-Q nanotethered test mass. The nanocavity frequency can be tuned to that of an input laser by on-chip capacitive actuators.
We propose, analyze, design, and take the first experimental steps towards the demonstration of an on-chip device capable of converting photons to phonons, and vice versa, in a nearly quantum-limited setting.
We demonstrate microwave frequency mechanical modes of optomechanical crystals having arbitrarily small clamping losses. The optomechanical crystals are connected to the substrate via a phononic bandgap structure, simultaneously isolating and rigidly supporting the optomechanical resonator.
We design, fabricate and measure high-Q mechanical modes (≈ 105) of optomechanical zipper cavities, as a first step to observing quantum back-action in an optomechanical system.
