Broadband silicon photonic phase shifters driven by gradient optical forces
Guillermo Arregui, Sander Jæger Linde, Magnus Vejby Nielsen +4
While initially deployed for optical interconnects, silicon photonics is increasingly being explored as a hardware platform for programmable optical systems, including linear optic…
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…
Nanoelectromechanical spectral control of silicon bowtie nanocavities for quantum light sources
Sergei Lepeshov, Daniel Alec Farbowitz, Thor August Schimmell Weis +4
We present the design, fabrication, and characterization of tunable waveguide-coupled silicon bowtie cavities with strong spatial electromagnetic field confinement. We use nanoelec…
Enhancement and speed-up of carrier dynamics in a dielectric nanocavity with deep sub-wavelength confinement
Gaoneng Dong, Ali Nawaz Babar, Rasmus Ellebæk Christiansen +4
The emergence of dielectric bowtie cavities enable optical confinement with ultrahigh quality factor and ultra-small optical mode volumes with perspectives for enhanced light-matte…
Waveguide and cavity quantum electrodynamics with topological bowtie modes
Anastasiia Vladimirova, Guillermo Arregui, Sergei Lepeshov +3
We present a theoretical study on photonic topological crystals whose symmetry is governed by quantum valley-Hall topological insulators and whose propagating edge modes are strong…
