Compact lithium niobate photonic integrated circuits
Yan Gao, Fuchuan Lei, Marcello Girardi +4
Lithium niobate (LN) is a promising material for future complex photonic-electronic circuits, with wide applications in fields like communications, sensing, quantum optics, and com…
Longitudinal piezoelectric resonant photoelastic modulator for efficient intensity modulation at megahertz frequencies
Okan Atalar, Raphaël Van Laer, Amir H. Safavi-Naeini +1
Intensity modulators are an essential component in optics for controlling free-space beams. Many applications require the intensity of a free-space beam to be modulated at a single…
Optomechanical antennas for on-chip beam-steering
Christopher Sarabalis, Raphaël Van Laer, Amir H. Safavi-Naeini
Rapid and low-power control over the direction of a radiating light field is a major challenge in photonics and a key enabling technology for emerging sensors and free-space commun…
Thermal Brillouin noise observed in silicon optomechanical waveguide
Raphaël Van Laer, Christopher J. Sarabalis, Roel Baets +2
Stimulated Brillouin scattering was recently observed in nanoscale silicon waveguides. Surprisingly, thermally-driven photon-phonon conversion in these structures had not yet been…
Brillouin resonance broadening due to structural variations in nanoscale waveguides
Christian Wolff, Raphael Van Laer, Michael J. Steel +2
We study the impact of structural variations (that is slowly varying geometry aberrations and internal strain fields) on the width and shape of the stimulated Brillouin scattering…
Net on-chip Brillouin gain based on suspended silicon nanowires
Raphaël Van Laer, Alexandre Bazin, Bart Kuyken +2
The century-old study of photon-phonon coupling has seen a remarkable revival in the past decade. Driven by early observations of dynamical back-action, the field progressed to gro…
Unifying Brillouin scattering and cavity optomechanics
Raphaël Van Laer, Roel Baets, Dries Van Thourhout
So far, Brillouin scattering and cavity optomechanics were mostly disconnected branches of research -- although both deal with photon-phonon coupling. This begs for the development…
Interaction between light and highly confined hypersound in a silicon photonic nanowire
Raphaël Van Laer, Bart Kuyken, Dries Van Thourhout +1
In the past decade, there has been a surge in research at the boundary between photonics and phononics. Most efforts centered on coupling light to motion in a high-quality optical…
