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…
Measurements, simulations, and models of the point-spread function of electron-beam lithography
Nikolaj B. Hougs, Kristian S. Knudsen, Marcus Albrechtsen +3
When a sample is exposed using electron-beam lithography, the electrons scatter deep and far in the substrate, resulting in unwanted deposition of dose at both the nano- and the mi…
Incoherent population trapping in quantum emitters
Sergei Lepeshov, Søren Stobbe
Deterministic emitters transform electronic excitations to photons with unity efficiency. Their development is crucial for both energy-efficient optical interconnects and photonic…
