Résumé

We describe the use of grown nanowires as scanning directional force sensors. Two orthogonal flexural modes are used to demonstrate vectorial sensing of electric and magnetic fields. Furthermore, we show that the modes can be strongly coupled by demonstrating Rabi oscillations. These results open the way to implement coherent control and frequency stabilization in nanomechanical force and mass sensors.

Frequency divider

A frequency divider, also called a clock divider or scaler or prescaler, is a circuit that takes an input signal of a frequency, , and generates an output signal of a frequency: where is an integer. Phase-locked loop frequency synthesizers make use of frequency dividers to generate a frequency that is a multiple of a reference frequency. Frequency dividers can be implemented for both analog and digital applications. Analog frequency dividers are less common and used only at very high frequencies.

Frequency synthesizer

A frequency synthesizer is an electronic circuit that generates a range of frequencies from a single reference frequency. Frequency synthesizers are used in many modern devices such as radio receivers, televisions, mobile telephones, radiotelephones, walkie-talkies, CB radios, cable television converter boxes, satellite receivers, and GPS systems. A frequency synthesizer may use the techniques of frequency multiplication, frequency division, direct digital synthesis, frequency mixing, and phase-locked loops to generate its frequencies.

Oscillateur commandé en tension

L’oscillateur commandé en tension ou VCO (pour Voltage Controlled Oscillator) est un oscillateur électronique qui émet un signal périodique dont la fréquence se stabilise en fonction de la tension d'entrée. C'est un montage typiquement utilisé dans les boucles à verrouillage de phase. Il permet ainsi de gérer la fréquence de sortie de la boucle de verrouillage, asservie avec la fréquence d'entrée. On retrouve également l'oscillateur commandé en tension en un ou plusieurs exemplaires dans les synthétiseurs analogiques.
