Coupled Flexural Optomechanical Cavities with Engineered Nanomechanical Interconnects
David Alonso-Tomás, Guillermo Arregui, Bingrui Lu +3
Integrated nanomechanical circuits require compact and predictable ways to read out, confine, and connect mechanical motion across multiple nanoscale elements. This challenge is pa…
Hybrid SiO2/Si Pillar-Based Optomechanical Crystals for On-Chip Photonic Integration
Martin Poblet, Christian Vinther Bertelsen, David Alonso-Tomas +8
One-dimensional photonic crystal (1D-PhC) pillar cavities allow transducing mechanical pillar vibrations to the optical domain, thereby relaxing the requirements typically associat…
Self-modulated multimode silicon cavity optomechanics
David Alonso-Tomás, Carlos Mas ArabÃ, Carles Milián +3
Multimode cavity optomechanics, where multiple mechanical degrees of freedom couple to optical cavity modes, provides a rich platform for exploring nonlinear dynamics and engineeri…
Cascaded injection locking of optomechanical crystal oscillators
David Alonso-Tomás, Guillermo Arregui, Laura Mercadé +4
Optomechanical oscillators stand out as high-performance and versatile candidates for serving as reference clocks in sequential photonic integrated circuits. Indeed, they have the…
Full Silicon Pillar-based 1D Optomechanical cavities
Juliana Jaramillo-Fernandez, Martin Poblet, David Alonso-Tomás +7
Nanomechanical resonators can serve as ultrasensitive, miniaturized force probes. While vertical structures like nanopillars are ideal for this purpose, transducing their motion is…
