Surpassing Fundamental Limits of Oscillators Using Nonlinear Resonators

In its most basic form an oscillator consists of a resonator driven on resonance, through feedback, to create a periodic signal sustained by a static energy source. The generation of a stable frequency, the basic function of oscillators, is typically achie ...

Phase noise measurement of external cavity diode lasers and implications for optomechanical sideband cooling of GHz mechanical modes

Tobias Kippenberg, Albert Schliesser

Cavity-optomechanical cooling via radiation pressure dynamical backaction enables ground-state cooling of mechanical oscillators, provided the laser exhibits sufficiently low phase noise. In this paper, we investigate and measure the excess phase noise of ...

Quantum-Coherent Coupling of a Mechanical Oscillator to an Optical Cavity Mode

Tobias Kippenberg, Albert Schliesser, Stefan Alexander Weis

We demonstrate an optomechanical microresonator in which optical and mechanical degrees of freedom exchange energy at a rate exceeding the relevant decoherence rates in the system, enabling quantum control of a mechanical oscillator with light. ...

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 ...

Determination of the vacuum optomechanical coupling rate using frequency noise calibration

Tobias Kippenberg, Albert Schliesser

The strength of optomechanical interactions in a cavity optomechanical system can be quantified by a vacuum coupling rate g(0) analogous to cavity quantum electrodynamics. This single figure of merit removes the ambiguity in the frequently quoted coupling ...

Cavity Optomechanics with Whispering-Gallery Mode Optical Micro-Resonators

Tobias Kippenberg, Albert Schliesser

Parametric coupling of optical and mechanical degrees of freedom forms the basis of many ultra-sensitive measurements of both force and mechanical displacement. An optical cavity with a mechanically compliant boundary enhances the optomechanical interactio ...

High-quality factor MEMS based oscillator: Silicon 9 MHz oscillator with low phase noise and high quality factor

Mihai Adrian Ionescu, Maher Kayal, Daniel Grogg, Fabrizio Lo Conte

In this paper, an oscillator based on a Vibrating Body Field Effect Transistor (VB-FET) working at 9.4MHz is presented. The electrical characteristics of this active MEM resonator are detailed for static and dynamic operation. The benefit of the intrinsic ...

Local tuning of the optical response of two-dimensional photonic crystals

Romuald Houdré, Libero Zuppiroli, Rolando Ferrini, Laurent Balet

Local tuning of the optical response of GaAs-based two dimensional photonic crystals (PhCs) is reported. A selective polymer infiltration technique was developed. Scanning electron microscopy and optical measurements were used to characterize the filled Ph ...
