Stabilization of a linear nanomechanical oscillator to its thermodynamic limit

Tobias Kippenberg, Emanuel Gavartin

The rapid development of micro- and nanomechanical oscillators in the past decade has led to the emergence of novel devices and sensors that are opening new frontiers in both applied and fundamental science. The potential of these devices is however affect ...

Universal formation dynamics and noise of Kerr-frequency combs in microresonators

Tobias Kippenberg, Tobias Herr, Emanuel Gavartin

Optical frequency combs allow for the precise measurement of optical frequencies and are used in a growing number of applications. The new class of Kerr-frequency comb sources, based on parametric frequency conversion in optical microresonators, can comple ...

A hybrid on-chip optomechanical transducer for ultrasensitive force measurements

Tobias Kippenberg, Emanuel Gavartin

Nanoscale mechanical oscillators(1) are used as ultrasensitive detectors of force(2), mass(3) and charge(4). Nanomechanical oscillators have also been coupled with optical and electronic resonators to explore the quantum properties of mechanical systems(5) ...

Universal Dynamics of Kerr-Frequency Comb Formation in Microresonators

Tobias Kippenberg, Tobias Herr, Emanuel Gavartin

We experimentally investigate the initial dynamics of Kerr-frequency comb formation in crystalline MgF2 and planar Si3N4 microresonator and present a universal, platform independent condition for low phase noise performance. ...

A versatile scheme for read-out and actuation of nanomechanical motion using silica microspheres

Tobias Kippenberg, Emanuel Gavartin

We employ silica microspheres to detect and actuate nanomechanical motion. With Si3N4-nanostrings, we achieve significant passive cooling by radiation pressure. Feedback-cooling enables stable operation at optical powers beyond the parametric-instability t ...

Phase Noise and Dispersion in integrated Silicon Nitride based Kerr-Comb generators

Tobias Kippenberg, Tobias Herr, Emanuel Gavartin

We report on measurements of phase noise dynamics of microwave beat notes observed in low repetition rate silicon nitride based Kerr-comb generators and relate them to results from dispersion simulations and measurements. (C) 2011 Optical Society of Americ ...

A hybrid on-chip optonanomechanical transducer for ultra-sensitive force measurements

Tobias Kippenberg, Emanuel Gavartin

We realize an integrated hybrid optonanomechanical transducer for the detection of weak forces. We propose and demonstrate with our system that dissipative feedback dramatically decreases the averaging time necessary to detect an incoherent force. (C) 2011 ...

Optomechanical sideband cooling of a micromechanical oscillator close to the quantum ground state

Tobias Kippenberg, Albert Schliesser, Emanuel Gavartin, Stefan Alexander Weis

Cooling a mesoscopic mechanical oscillator to its quantum ground state is elementary for the preparation and control of quantum states of mechanical objects. Here, we pre-cool a 70-MHz micromechanical silica oscillator to an occupancy below 200 quanta by t ...
