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…
Single mode waveguide platform for spontaneous and surface-enhanced on-chip Raman spectroscopy
Ashim Dhakal, Frédéric Peyskens, Stéphane Clemmen +5
We review an on-chip approach for spontaneous Raman spectroscopy and Surface Enhanced Raman Spectroscopy (SERS) based on evanescent excitation of the analyte as well as evanescent…
Nanophotonic waveguide enhanced Raman spectroscopy of biological submonolayers
Ashim Dhakal, Pieter C. Wuytens, Frédéric Peyskens +3
Characterizing a monolayer of biological molecules has been a major challenge. We demonstrate nanophotonic wave-guide enhanced Raman spectroscopy (NWERS) of monolayers in the near-…
