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…

Computing with the complex nonlinear dynamics of an optomechanical oscillator

Shulamit Edelstein, Marcos Menendez, Bingrui Lu +5

An optomechanical oscillator undergoes a Hopf bifurcation that connects two dynamical regimes with different information-processing capabilities: thermal Brownian motion and cohere…
