We experimentally demonstrate a negative Kerr nonlinearity for quasiundoped graphene.
Hereto, we introduce the method of chirped-pulse-pumped self-phase modulation and apply …

In this paper, we numerically investigate near-and mid-infrared supercontinuum (SC)
generation in dispersion-engineered silicon-on-insulator (SOI) waveguides employing a …

To meet the increasing demand for data communication bandwidth and overcome the limits
of electrical interconnects, silicon photonic technology has been extensively studied, with …

Supercontinuum generation in the anomalous group-velocity dispersion regime is widely
considered to be inherently unstable against input pulse fluctuations. This constraint has …

A fully analytical toolbox for supercontinuum generation relying on scenarios without pulse
splitting is presented. Furthermore, starting from the new insights provided by this formalism …

Silicon is a widely used material due to its strong properties especially low loss and high
nonlinearity in the wavelength range 1.2–6 μm. Also, photonic crystal fibers (PCFs) have …

No general approach is available yet to measure directly the ratio between chromatic
dispersion and the nonlinear coefficient, and hence the soliton number for a given optical …

We numerically show the advantages of using diamond-on-insulator (DOI) waveguides to
design compact supercontinuum (SC) light sources for the visible (VIS) wavelength range …

Nonlinear propagation of light pulses can excite dispersive waves anchored at frequencies
determined by the chromatic dispersion curve. In this work, conditions enabling dispersive …

We design and simulate a near-zero flat dispersion As2S3 photonic crystal fiber (PCF) with a
circular shape to generate a broad and smooth supercontinuum (SC). A near-zero flattened …
