Micromechanical Resonator Driven by Radiation Pressure Force

Abstract

Radiation pressure exerted by light on any surface is the pressure generated by the momentum of impinging photons. The associated force – fundamentally, a quantum mechanical aspect of light – is usually too small to be useful, except in large-scale problems in astronomy and astrodynamics. In atomic and molecular optics, radiation pressure can be used to trap or cool atoms and ions. Use of radiation pressure on larger objects such as micromechanical resonators has been so far limited to its coupling to an acoustic mode, sideband cooling, or levitation of microscopic objects. In this Letter, we demonstrate direct actuation of a radio-frequency micromechanical plate-type resonator by the radiation pressure force generated by a standard laser diode at room temperature. Using two independent methods, the magnitude of the resonator’s response to forcing by radiation pressure is found to be proportional to the intensity of the incident light.

Measurement of nonlinear piezoelectric coefficients using a micromechanical resonator

“…Piezoelectric materials provide a convenient way to convert between mechanical displacements or vibrations and electrical signals. As such, there are frequent publications on using piezoelectrics for energy harvesting [10,11], communication [12,13], force measurements [14][15][16], and high-precision motion [17,18], among other applications. In many of these applications, it is desirable to reduce the size of every component of the system as much as possible.…”

Impact of the Central Frequency of Environment on Non-Markovian Dynamics in Piezoelectric Optomechanical Devices

“…Optomechanical systems have received substantial interests as a promising experimental platform to improve the resolution and precision of measurement to beat the standard quantum limit, to observe macroscopic quantum phenomena, and to realize sideband cooling and parametric amplification [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] . Its applications, ranging from quantum information to quantum sensing, have been thoroughly studied.…”

Terahertz oscillatory radiation torque at the microscale

“…Recent advances in nanotechnology have triggered a quest for fast nano-mechanical oscillators which could benefit many fields such as nanomachines [1,2], telecommunication [3,4], and also medical applications [5][6][7]. Several approaches have been developed including (but not limited to) carbon nanotube based approaches [8,9], and also approaches based on the optical force [10][11][12][13][14]. While the optically-based linear vibrational oscillators rely on the exchange of linear momentum between light and matter, the torsional and rotational opticallybased ones rely on the exchange of angular momentum [15] (spin and/or orbital).…”
