Ultra-sensitive refractive index gas sensor with functionalized silicon nitride photonic circuits
Giuseppe Antonacci, Jeroen Goyvaerts, Haolan Zhao +3
Portable and cost-effective gas sensors are gaining demand for a number of environmental, biomedical and industrial applications, yet current devices are confined into specialized…
Controlling phonons and photons at the wavelength-scale: silicon photonics meets silicon phononics
Amir H. Safavi-Naeini, Dries Van Thourhout, Roel Baets +1
Radio-frequency communication systems have long used bulk- and surface-acoustic-wave devices supporting ultrasonic mechanical waves to manipulate and sense signals. These devices h…
Enhancement of bulk second-harmonic generation from silicon nitride films by material composition
K. Koskinen, R. Czaplicki, A. Slablab +8
We present a comprehensive tensorial characterization of second-harmonic generation from silicon nitride films with varying composition. The samples were fabricated using plasma-en…
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…

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…
Atomic layer deposited second order nonlinear optical metamaterial for back-end integration with CMOS-compatible nanophotonic circuitry
StÉphane Clemmen, Artur Hermans, Eduardo Solano +6
We report the fabrication of artificial unidimensional crystals exhibiting an effective bulk second-order nonlinearity. The crystals are created by cycling atomic layer deposition…
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…
