Through optomechanical experiments in a semiconductor micro-resonator, researchers from the DON team of the MPQ laboratory, in collaboration with the Center for Nanoscience and Nanotechnology, have shown that a coupling between different forms of energy can give rise to a stable pulsed mechanical motion at ultra-high frequency.

Evolution of the mechanical frequency comb generated within an optomechanical micro-resonator. The resulting ultra-high frequency spectrum is shown as a function of the driving laser wavelength. Experiment (top); theory (bottom).
This discovery could enrich micro-mechanical technologies (accelerometers, force sensors, magnetometers, mass sensors), particularly in the ultra-high frequency range, where pulsed mechanical techniques are scarce.
These results, published in Phys. Rev. Lett, have been chosen as the journal cover, and covered by a news article on the INP website.
