Mid-Infrared Supercontinuum Generation in a Pure Germanium-on-Silicon Ridge Waveguide

Broad mid-IR supercontinuum is traditionally generated via soliton fission, as obtained by pumping a nonlinear waveguide with an anomalous dispersion, close to the zero dispersion

Supercontinuum generation up to 8.5 µm has been demonstrated by our group in silicon- germanium on silicon waveguides, reaching the onset of the absorption from the silicon

Supercontinuum generation up to 8.5 µm has been demonstrated by our group in silicon-germanium on silicon waveguides, reaching the onset of the absorption from the

As a flat profile of the dispersion is generally targeted for SC generation, both in the anomalous and in the normal dispersion regime, the possibility of controlling

Here, we demonstrate the generation of 1.4 octave spanning supercontinuum in the MWIR from 2.6 to 7.3μm with a useful on-chip average power greater than 7mW by pumping

In this work, we report what we believe to be the first octave-spanning fully coherent supercontinuum in an ANDi waveguide on a silicon-based chip in the mid-infrared.. A SiGe

Indeed, simulations considering constant α FC predict SC generation up to 7 µm (fig. 1b, bottom, green curve), whereas simulations including the wavelength dependence of α FC

Recently, silicon-germanium (SiGe) alloys, have emerged as an attractive alternative platform for mid-IR photonics [9-11], with transparency potentially extending
