We demonstrate substrate-transferred crystalline coatings, based on epitaxial Bragg mirrors directly-bonded to fused silica, exhibiting an unprecedented tenfold reduction in Brownian noise. These mirrors promise a significant advancement in the performance of precision optical interferometers.
In an interferometric measurement, the quantum radiation pressure noise, which is due to quantum intracavity intensity fluctuations, gives rise to mirror displacement fluctuations and sets a limit in the displacement sensitivity. We have designed a table-top experiment to demonstrate this effect and realize various quantum optics experiments with an optomechanical system.
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 describe coupled-cavity scheme to achieve ground-state cooling of mechanical motion in highly-unresolved sideband regimes. Through EIT lineshapes, both quantum Langevin and master equations confirm the quantum noise characteristics and achieve κ/ωm greater than 104.
We demonstrate a high-efficiency optical-fiber coupling platform for optomechanical cavities. Through adiabatic mode conversion, a continuous position measurement with an imprecision of only 0.7 phonons at the optimal standard quantum limit probe power is achieved.
