Abstract
Nanoelectromechanical systems could have applications in fields as diverse as ultrasensitive mass detection1, 2, 3 and mechanical computation4, 5, 6, and can also be used to explore fundamental phenomena such as quantized heat conductance7 and quantum-limited displacement8, 9. Most nanomechanical studies to date have been performed in the frequency domain. However, applications in computation10 and information storage11 will require transient excitation and high-speed time-domain operation of nanomechanical systems. Here we show a time-resolved optical approach to the transduction of ultrahigh-frequency nanoelectromechanical systems, and demonstrate that coherent control of nanomechanical oscillation is possible through appropriate pulse programming. A series of cantilevers with resonant frequencies ranging from less than 10 MHz to over 1 GHz are characterized using the same pulse parameters.
