Photonic Frequency Conversion of OFDM Microwave Signals in a Wavelength-Scale Optomechanical Cavity
Laura Mercadé, Maria Morant, Amadeu Griol +2
Optomechanical (OM) cavities enable coupling of near-infrared light and GHz-frequency acoustic waves in wavelength-scale volumes. When driven in the phonon lasing regime, an OM cav…
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…
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…
Dispersive optomechanics of supercavity modes in high-index disks
Laura Mercadé, Ángela Barreda, Alejandro Martínez
In this work, we study the dispersive coupling between optical quasi-bound-states in the continuum at telecom wavelengths and GHz-mechanical modes in high-index wavelength-sized di…
Exploiting metamaterials, plasmonics and nanoantennas concepts in silicon photonics
Francisco J. Rodríguez-Fortuño, Alba Espinosa-Soria, Alejandro Martínez
The interaction of light with subwavelength metallic nano-structures is at the heart of different current scientific hot topics, namely plasmonics, metamaterials and nanoantennas.…
Microwave generation and frequency comb in a silicon optomechanical cavity with a full phononic bandgap
Laura Mercadé, Leopoldo L. Martín, Amadeu Griol +2
Cavity optomechanics has become a powerful tool to manipulate mechanical motion via optical fields. When driving an optomechanical cavity with blue-detuned laser the mechanical mot…
