Active Microelectromechanical Resonator

Daniel Grogg

The progress in the technology of microelectronic devices has led to a strong miniaturization and high performance for circuits and systems, enabling modern applications such as mobile computing and communications. Today, remaining "off-chip" components th ...

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 ...

Thermal effects in the Long-Term Monitoring of Bridges

Olivier Burdet

Daily and seasonal temperature variations induce deflections of bridges. The amplitude of these moments is significant in comparison with the yearly increment caused by irreversible long-term deflections. To improve the quality of the interpretation of mon ...

Ink-jet printed colorimetric gas sensors on plastic foil

Nico de Rooij, Danick Briand, Jérôme Courbat

An all polymeric colorimetric gas sensor with its associated electronics for ammonia (NH3) detection targeting low-cost and low-power applications is presented. The gas sensitive layer was inkjet printed on a plastic foil. The use of the foil directly as o ...

Measuring nanomechanical motion with an imprecision below the standard quantum limit

Tobias Kippenberg, Emanuel Gavartin

We report a room-temperature measurement of nanomechanical motion with an imprecision below the standard quantum limit (SQL), using cavity-enhanced optical near fields. Fundamental thermodynamical cavity frequency fluctuation limits the total imprecision t ...

Anomalous dielectric peak in Mg and Li doped ZnO ceramics and thin films

Nava Setter, Alexander Tagantsev

In this manuscript we report dielectric measurements of Mg and Li doped ZnO ceramics and thin films of various compositions. We have tried to reproduce the reported ferroelectriclike behavior in doped ZnO ceramics and thin films and observed anomalous diel ...

Cavity optomechanics with ultrahigh-Q crystalline microresonators

Tobias Kippenberg, Albert Schliesser

We present the observation of optomechanical coupling in crystalline whispering-gallery-mode (WGM) resonators. The high purity of the material enables optical quality factors in excess of 10(10) and finesse exceeding 10(6), as well as mechanical quality fa ...

Silicon Resonator Based 3.2 mu W Real Time Clock With +/- 10 ppm Frequency Accuracy

David Ruffieux, François Krummenacher, Aurélie Pezous

This paper presents an ultra-low power generic compensation scheme that is used to implement a real time clock based on an AlN-driven 1 MHz uncompensated silicon resonator achieving 3.2 mu W power dissipation at 1 V and +/- 10 ppm frequency accuracy over a ...

A high-reflectivity atom-focusing mirror stable at room temperature

It is shown that the Pb(root 3x root 3)R30/Si(111) ordered layer is an excellent mirror for neutral He atoms. It focuses more than 15% of the incoming He atoms into the specular peak, and is stable up to 450 K. Moreover, the reflectivity remains almost unc ...
