TL;DR: In this paper, the authors experimentally and theoretically demonstrate stimulated Brillouin scattering in a silicon nanowire supported by a pillar, which results from the tight confinement of both photons and phonons.

TL;DR: In this paper, the advantages and challenges associated with these two material platforms are discussed, and the case of dispersive spectrometers, which are widely used in various silicon photonic applications, is presented.

TL;DR: This work takes a different approach to spectral broadening of mid-infrared frequency combs and investigates CMOS-compatible highly nonlinear dispersion-engineered silicon nanophotonic waveguides on a silicon-on-insulator chip and demonstrates phase-coherent comb spectra broadened on a room-temperature-operating CMos-compatible chip.

TL;DR: In this paper, the development of silicon and silicon nitride (Si3N4) integrated photonic integrated circuits for various spectroscopic sensing applications is presented, including waveguide-based absorption and Raman and surface enhanced Raman spectroscopy.

TL;DR: The generation of a supercontinuum is demonstrated by pumping the wire with mid-infrared picosecond pulses in the anomalous dispersion regime by extracting the group velocity dispersion and fourth-order dispersion coefficient of the silicon wire waveguide.
