We review recent advances related to slow light in periodic structures, where the refractive
index varies along one or two directions, ie gratings and planar photonic crystals. We focus …

Laser frequency combs, sources with a spectrum consisting of hundred thousands evenly
spaced narrow lines, have an exhilarating potential for new approaches to molecular …

Nonlinear integrated optics leveraging platforms with high nonlinear figure of merit offer
energy efficient optical signal processing capabilities. Over the last five years, CMOS …

Solitons are nonlinear waves present in diverse physical systems including plasmas, water
surfaces and optics. In silicon, the presence of two photon absorption and accompanying …

Solitons are nonlinear waves that exhibit invariant or recurrent behaviour as they propagate.
Precise control of dispersion and nonlinear effects governs soliton propagation and, through …

There are two standard methods for controlling the group velocity of light. One makes use of
the dispersive properties associated with the resonance structure of a material medium. The …

We have investigated the nonlinear optical response of low loss Si_0. 6Ge_0. 4/Si
waveguides in the mid-infrared wavelength range from 3.25-4.75 μm using picosecond …

We experimentally investigate four-wave mixing (FWM) in short (80 μm) dispersion-
engineered slow light silicon photonic crystal waveguides. The pump, probe and idler …

Using Fourier optics, we retrieve the wavevector dependence of the third-harmonic (green)
light generated in a slow light silicon photonic crystal waveguide. We show that quasi-phase …

Silicon carbide (SiC) is considered a promising platform for linear and nonlinear photonics
due to its large band gap, large refractive index, low thermo-optic coefficient, large Kerr …
