Excitation and detection of acoustic phonons in nanoscale systems
Ryan C Ng, Alexandros El Sachat, Francisco Cespedes +8
Phonons play a key role in the physical properties of materials, and have long been a topic of study in physics. While the effects of phonons had historically been considered to be…
Room-temperature silicon platform for GHz-frequency nano-electro-opto-mechanical systems
D. Navarro-Urrios, M. F. Colombano, G. Arregui +7
Nano-electro-opto-mechanical systems enable the synergistic coexistence of electrical, mechanical, and optical signals on a chip to realize new functions. Most of the technology pl…
Thermal properties of nanocrystalline silicon nanobeams
Jeremie Maire, Emigdio Chavez-Angel, Guillermo Arregui +7
Controlling thermal energy transfer at the nanoscale has become critically important in many applications and thermal properties since it often limits device performance. In this w…
Optomechanical crystals for spatial sensing of submicron sized analytes
D. Navarro-Urrios, E. Kang, P. Xiao +7
Optomechanical crystal cavities have rich perspectives for detecting and indirectly analysing biological particles, such as proteins, bacteria and viruses. In this work we demonstr…
Injection locking in an optomechanical coherent phonon source
Guillermo Arregui, Martin Facundo Colombano, Jérémie Maire +6
Spontaneous locking of the phase of a coherent phonon source to an external reference is demonstrated in an optomechanical oscillator based on a self-triggered free-carrier/tempera…
Quantifying the robustness of topological slow light
Guillermo Arregui, Jordi Gomis-Bresco, Clivia Marfa Sotomayor-Torres +1
Low-dimensional nanostructured materials can guide light propagating with very low group velocity vg. However, this slow light is significantly sensitive to unwanted imperfections…
