[EN] Locking of oscillators to ultra-stable external sources is of paramount importance for improving close-to-carrier phase noise in free running oscillators. In most of them, such as Micro-Electro-Mechanical-Systems or ...
[EN] Spontaneous locking of the phase of a coherent phonon source to an external reference is demonstrated in a deeply sideband-unresolved optomechanical system. The high-amplitude mechanical oscillations are driven by the ...
[EN] Cavity optomechanics has recently emerged as a new paradigm enabling the manipulation of mechanical motion via optical fields tightly confined in deformable cavities. When driving an optomechanical (OM) crystal cavity ...
[EN] Optical nonlinearities, such as thermo-optic mechanisms and free-carrier dispersion, are often considered unwelcome effects in silicon-based resonators and, more specifically, optomechanical cavities, since they affect, ...
[EN] The interaction between phonons and photons is investigated theoretically in a phoxonic cavity inside a
corrugated nanobeam waveguide presenting band gaps for both electromagnetic and elastic waves. The structure
is ...
[EN] Elusive features in photonic and electronic devices can be detected by means of advanced, time-domain spectroscopic techniques. In this paper we introduce a modulation spectroscopy based on the optomechanical interaction ...
[EN] Nanocrystalline materials exhibit properties that can differ substantially from those of their single crystal counterparts. As such, they provide ways to enhance and optimize their functionality for devices and ...
[EN] Nanoelectro-opto-mechanical systems enable the synergistic coexistence of electrical, mechanical, and optical signals on a chip to realize new functions. Most of the technology platforms proposed for the fabrication ...

A novel Y3(1-x)Er3xGa5O12 nanocrystalline garnet has been synthesized by a sol-gel technique and a complete structural, morphological, vibrational, and optical characterization has been carried out in order to correlate ...
[EN] Controlling thermal energy transfer at the nanoscale and thermal properties has become critically important in many applications since it often
limits device performance. In this study, the effects on thermal conductivity ...
